Bathroom Remodeling in Houston: Plan and Hire
For Bathroom Remodeling in Houston, give contractors the same written scope, identify who will handle plumbing, and confirm permit responsibility before agreeing to demolition. The Texas plumbing regulator recommends checking the company's Responsible Master Plumber, license validity, and insurance record, then obtaining detailed written estimates. Ask each bidder to separate the construction price, allowances, permit charges, and tax treatment so you can compare the work you will receive. [3]
Define the bathroom you want before requesting bids
Write down what you want to keep, replace, and move. Include the vanity, toilet, tub or shower, floor, lighting, and exhaust fan. Give each bidder photos and the same sketch showing current and proposed fixture locations. Ask for separate options if you are deciding between keeping the layout and moving fixtures.
For shower work, request a description of demolition, wall and floor preparation, waterproofing, drain connections, tile, and glass. Ask who will check the installation before anyone covers it. For easier access, describe your needs for the entry threshold, seat, grab bars, and usable space before selecting finishes.
Tell the contractor whether this is your only bathroom. Agree on toilet and shower access during construction, water shutoff notice, work hours, dust protection, and debris removal. Request a schedule that identifies material delivery, inspections, and the point when you can use the room again.
Check the plumbing subcontractor behind the remodel
The Texas State Board of Plumbing Examiners advises consumers to obtain the company's Responsible Master Plumber name and check that person's Master Plumber license and insurance certificate through its license search. Ask the remodeling contractor to identify the plumbing company before you sign, then follow the public-license-search link on the board's consumer information page. [3]
The board also recommends checking with the local municipal plumbing inspection department about the company's eligibility to work in the city and whether the proposed work requires permits and inspections. Give the department your project description, including fixture replacements and relocations, rather than asking about a bathroom remodel without describing the work. [3]
The board says written plumbing estimates and invoices should include the Responsible Master Plumber's license number and the board's name, address, and telephone number. It recommends several estimates, written warranties, and checking references. Ask references about communication, completion, and how the contractor handled repairs after the job. [3]
Compare complete bids and material allowances
Compare demolition, disposal, preparation, installation, finishes, and cleanup line by line. Ask each contractor to identify exclusions and owner-supplied items. For an allowance, request the dollar amount, the item it covers, and whether delivery and installation belong in that amount. Choose fixture models before signing when you can.
Require a written change-order process for damage discovered after demolition. Ask the contractor to photograph the condition, describe the repair, and provide the added price and schedule effect for your approval. Keep a separate reserve that you control rather than authorizing an undefined amount of extra work.
Ask for payment milestones tied to described work and a written warranty with a contact for service. At handover, request the applicable inspection records, product information, care instructions, and a list of unfinished items. Use a walkthrough to check fixture operation, drainage, fan operation, doors, and visible finishes.
Read Houston permit fees as part of the budget
Houston's fee schedule lists plumbing fixture charges of $34.24 for one to three units and $11.41 for each fixture beyond three on the same permit. It also lists a $97.56 plumbing minimum permit fee, with these amounts effective January 1, 2026. Ask for the city's calculation for your scope; do not treat the fixture charge as the complete permit cost. [1]
The schedule lists a $91.06 electrical minimum permit fee and a $94.00 permit charge for local vents, central vacuum systems, and ventilation fans up to 2,000 cfm. Houston warns that listed fees may carry an administrative fee and directs readers to the relevant department or 311. Have the bidder identify the applicable permits and any added charges before you accept a permit allowance. [1]
Check how the contractor handles Texas sales tax
The Texas Comptroller states that labor to repair or remodel residential real property is not taxable. Under a residential lump-sum contract, the contractor pays tax when buying supplies, materials, equipment, and taxable services and does not charge the customer tax. Ask the bidder to state whether the proposed agreement uses this contract type. [2]
Under a separated residential contract, the contractor collects state and applicable local tax on charges for incorporated materials and certain services; the construction labor charge remains nontaxable. Request a clear explanation of the taxable invoice items. Itemizing a bid for comparison does not, by itself, explain how the contractor will structure your agreement. [2]

Resolve the fixture-charge and permit-minimum difference
For work under Houston's permitting authority, ask the contractor to reconcile the $34.24 charge for one to three plumbing fixtures with the $97.56 plumbing minimum permit fee. The city lists both, effective January 1, 2026. Request the applicable city fee calculation and identify administrative charges before approving the allowance. [1]
Choose the contract type before comparing tax totals
Texas residential tax rules apply to this home remodel: a lump-sum contractor pays tax on purchases without charging you tax, while a separated contractor collects tax on incorporated materials and certain services. Residential construction labor remains nontaxable. Ask each bidder to identify the contract type and explain any customer tax line before comparing final totals. [2]
