Accounting Policies [Abstract]	'
Organization and Significant Accounting Policies	'
	(1) Organization and Significant Accounting Policies
	Organization. Sunshine Bancorp, Inc., a Maryland corporation (the “Holding Company”), was formed on March 7, 2014 to serve as the savings and loan holding company for Sunshine State Bank (the “Bank”). The Holding Company was formed as part of the Bank’s mutual-to-stock conversion (the “Conversion”). Collectively, the Bank and Holding Company are referred to as the “Company.” The accounting and reporting policies conform to U.S. generally accepted accounting principles (GAAP) and general practices within the banking industry and are described in note 1 to the financial statements in 2013, as updated by the information in this Form 10-Q
	On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the bank.
	In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of the stock issued in the conversion were acquired by the ESOP.
	The Bank through its five banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough and Pasco Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation. The financial statements of the Company have been prepared to conform to accounting principles generally accepted in the United States of America (“GAAP”) and to prevailing practices within the banking industry.
	As part of the Conversion, the Holding Company established a liquidation account in an amount equal to retained income of $26.6 million contained in the final prospectus. The liquidation account will be maintained for the benefit of eligible account holders who maintain deposit accounts in the Bank after the conversion.
	Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Holding Company and the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements in this report have not been audited except for information derived from our audited 2013 financial statements. Financial information prior to July 14, 2014 is of the Bank only.
	In the opinion of management, the accompanying condensed consolidated financial statements of the Company contain all adjustments (consisting principally of normal recurring accruals) necessary to present fairly the financial position at September 30, 2014, and the results of operations for the three and nine month periods ended September 30, 2014 and 2013. The results of operations for the three and nine months ended September 30, 2014, are not necessarily indicative of the results to be expected for the full year or any other period.
	Income Per Share. The conversion was complete on July 14, 2014. Income per share will be computed starting on October 1, 2014, as if conversion from a mutual holding company to a capital stock holding company occurred on that date.
	Recent Accounting Standards Update. In January 2014, the FASB issued ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, which is intended to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. The amendments are effective beginning January 1, 2015. Upon adoption, this guidance is not expected to impact the Bank’s financial statements.
	In June 2014, FASB issued ASU 2014-11, Transfers and Servicing - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. ASU 2014-11 requires, among other things, two accounting changes. First, the amendments in this update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. Second, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. ASU 2014-11 is effective for the first interim or annual period beginning after December 15, 2014. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements.
	In June 2014, FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 requires, among other things, that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements.
	Recent Regulatory Developments
	Basel III Rules. On July 2, 2013, the Federal Reserve Board (“FRB”) approved the final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks. Under the final rules, minimum requirements will increase for both the quantity and quality of capital held by the Bank. The rules include a new common equity Tier 1 capital to risk-weighted assets ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets. The final rules also raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% and require a minimum leverage ratio of 4.0%. The final rules also implement strict eligibility criteria for regulatory capital instruments. In July 2013, the Office of the Comptroller of the Currency (“OCC”), our primary bank regulator, also approved, as an interim final rule, the regulatory capital requirements for U.S. banks, following the actions of the FRB. The OCC’s rule is identical in substance to the final rules issued by the FRB.
	The phase-in period for the final rules will begin for the Holding Company and the Bank on January 1, 2015, with full compliance with all of the final rule’s requirements phased in over a multi-year schedule. The Bank is currently evaluating the provisions of the final rules and their expected impact on the Bank.

	The unrealized losses on twenty-six investment securities held to maturity at September 30, 2014 were caused by market conditions. It is expected that the securities would not be settled at a price less than the par value of the investments. Because the decline in fair value is attributable to market conditions and not credit quality, and because the Company has the ability and intent to hold these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily impaired.
	Securities with a carrying amount of approximately $2.0 million at September 30, 2014 and December 31, 2013 were pledged to the Housing Authority of the City of Plant City, Florida for deposit accounts held at the Company.

	Loans, net	$	110,936			111,263
	The Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics and methodologies for assessing risk. All loans are underwritten in accordance with policies set forth and approved by the Company’s board of directors. The portfolio segments identified by the Company are as follows:
	Real Estate Mortgage Loans. Real estate mortgage loans are typically segmented into four classes: one-to four-family residential, commercial, multi-family and land and construction.
	One-to four-family residential real estate loans are underwritten based on repayment capacity and source, value of the underlying property, credit history and stability.
	Commercial real estate loans are secured by the subject property. Underwriting standards include, among other factors, loan to value limits, cash flow coverage and general creditworthiness of the obligors.
	Multi-family real estate loans follow the same underwriting criteria as commercial real estate loans. These loans are generally considered to have more credit risk than traditional one-to four-family residential loans because these loans tend to involve larger loan balances and their repayment is typically dependent upon the successful operation and management of the underlying real estate.
	Land and construction loans are to finance the construction of owner-occupied and lease properties. These loans are categorized as construction loans during the construction period, later converting to commercial or one-to four-family residential real estate loans after the construction is complete and amortization of the loan begins. Real estate development and construction loans are approved based on an analysis of the borrower and guarantor, the viability of the project and on an acceptable percentage of the appraised value of the property securing the loan. Real estate development and construction loan funds are disbursed periodically based on the percentage of construction completed. The Company carefully monitors these loans with on-site inspections and requires the receipt of lien waivers on funds advanced. Development and construction loans are typically secured by the properties under development or construction, and personal guarantees are typically obtained. Further, to assure that reliance is not placed solely on the value of the underlying property, the Company considers the market conditions and feasibility of proposed projects, the financial condition and reputation of the borrower and guarantors, the amount of the borrower’s equity in the project, independent appraisals, cost estimates and pre-construction sale information. The Company also makes loans on occasion for the purchase of land for future development by the borrower. Land loans are extended for the future development for either commercial or residential use by the borrower. The Company carefully analyzes the intended use of the property and the viability thereof.
	Commercial Loans. Commercial loans are primarily underwritten on the basis of the borrowers’ ability to service such debt from income. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. As a general practice, the Company takes as collateral a security interest in any available real estate, equipment, or other chattel, although loans may also be made on an unsecured basis. Collateralized working capital loans typically are secured by short-term assets whereas long-term loans are primarily secured by long-term assets.
	Consumer Loans. Consumer loans are extended for various purposes, including purchases of automobiles, recreational vehicles, and boats. The Company also offers lines of credit, personal loans, and deposit account collateralized loans. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Loans to consumers are extended after a credit evaluation, including the creditworthiness of the borrower(s), the purpose of the credit, and the secondary source of repayment. Consumer loans are made at fixed interest rates and may be made on terms of up to five years. Risk is mitigated by the fact that the loans are of smaller individual amounts.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors.
The Company analyzes loans individually by classifying the loans as to credit risk. Loans classified as substandard or special mention are reviewed quarterly by the Company for further deterioration or improvement to determine if they are appropriately classified and whether there is any impairment. All loans are graded upon initial issuance. Further, commercial, multi-family and commercial real estate loans over $25,000 are typically reviewed at least annually to determine the appropriate loan grading. In addition, during the renewal process of any loan, as well as if a loan becomes past due, the Company will determine the appropriate loan grade.
Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of a deterioration in the credit worthiness of the borrower; or (c) the borrower contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard or even charged-off. The Company uses the following definitions for risk ratings:
Pass – A Pass loan’s primary source of loan repayment is satisfactory, with secondary sources very likely to be realized if necessary.
Special Mention – A Special Mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.
Substandard – A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful – A loan classified Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristics that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. At September 30, 2014 and December 31, 2013, the Company had no loans listed as doubtful in its loan credit quality.
Loss – A loan classified Loss is considered uncollectible and of such little value that continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be affected in the future. At September 30, 2014 and December 31, 2013, the Company had no loans listed as loss in its loan credit quality.

The allowance for loan losses on all loans that have been restructured and are considered TDRs is included in the Bank’s specific allowance for loan losses. The specific allowance for loan losses is determined on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral-dependent. TDRs that have subsequently defaulted are considered collateral-dependent.
During the three and nine months ended September 30, 2014 and 2013, the Company had no loans restructured as troubled debt restructurings that subsequently defaulted that had been modified in the previous twelve month period.

Organization and Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
Organization	'
	Organization. Sunshine Bancorp, Inc., a Maryland corporation (the “Holding Company”), was formed on March 7, 2014 to serve as the savings and loan holding company for Sunshine State Bank (the “Bank”). The Holding Company was formed as part of the Bank’s mutual-to-stock conversion (the “Conversion”). Collectively, the Bank and Holding Company are referred to as the “Company.” The accounting and reporting policies conform to U.S. generally accepted accounting principles (GAAP) and general practices within the banking industry and are described in note 1 to the financial statements in 2013, as updated by the information in this Form 10-Q
	On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the bank.
	In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of the stock issued in the conversion were acquired by the ESOP.
	The Bank through its five banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough and Pasco Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation. The financial statements of the Company have been prepared to conform to accounting principles generally accepted in the United States of America (“GAAP”) and to prevailing practices within the banking industry.
	As part of the Conversion, the Holding Company established a liquidation account in an amount equal to retained income of $26.6 million contained in the final prospectus. The liquidation account will be maintained for the benefit of eligible account holders who maintain deposit accounts in the Bank after the conversion.
Principles of Consolidation	'
	Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Holding Company and the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements in this report have not been audited except for information derived from our audited 2013 financial statements. Financial information prior to July 14, 2014 is of the Bank only.
	In the opinion of management, the accompanying condensed consolidated financial statements of the Company contain all adjustments (consisting principally of normal recurring accruals) necessary to present fairly the financial position at September 30, 2014, and the results of operations for the three and nine month periods ended September 30, 2014 and 2013. The results of operations for the three and nine months ended September 30, 2014, are not necessarily indicative of the results to be expected for the full year or any other period.
Recent Accounting Standards Update	'
	Recent Accounting Standards Update. In January 2014, the FASB issued ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, which is intended to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. The amendments are effective beginning January 1, 2015. Upon adoption, this guidance is not expected to impact the Bank’s financial statements.
	In June 2014, FASB issued ASU 2014-11, Transfers and Servicing - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. ASU 2014-11 requires, among other things, two accounting changes. First, the amendments in this update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. Second, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. ASU 2014-11 is effective for the first interim or annual period beginning after December 15, 2014. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements.
	In June 2014, FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 requires, among other things, that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements.
Earnings Per Share	'
	Income Per Share. The conversion was complete on July 14, 2014. Income per share will be computed starting on October 1, 2014, as if conversion from a mutual holding company to a capital stock holding company occurred on that date.
