Bathroom Remodeling in Texas

There is no statewide general contractor or remodeler license in Texas. However, any plumbing work must be done by a plumber licensed through the Texas State Board of Plumbing Examiners (TSBPE), and electrical work by a TDLR-licensed electrician. Many cities also require contractors to register locally. Always verify the plumbing license via TSBPE's public license search.

National benchmarks track Texas well: the average bathroom remodel is $12,142, with most projects between $2,500 and $30,000 (Angi 2026). A midrange full remodel averages $26,138 and recoups about 80% at resale; a universal-design bathroom averages $42,183 and recoups about 61% (Zonda Cost vs. Value 2025).

Winter Storm Uri in February 2021 generated more than 500,000 insurance claims and roughly $10.3 billion in expected insured losses (Texas Department of Insurance; Insurance Council of Texas), mostly from burst pipes and water damage. If you're remodeling, take the lesson: keep supply lines out of exterior walls and attics where possible, insulate what remains, consider PEX piping, and install accessible shutoff valves.

Permits are municipal in Texas. Houston, San Antonio, and Dallas all require permits when you move or add plumbing fixtures, alter drains, or change electrical circuits; simple like-for-like fixture swaps usually don't. In unincorporated areas, requirements are lighter but licensed-trade rules still apply. Your contractor should handle permitting.

Much of Texas sits on limestone aquifers, and water is often 'very hard' — above 180 mg/L by USGS classification. San Antonio's utility reports typical hardness of 15–20 grains per gallon (SAWS). Hard water scales showerheads, valves, glass, and water heaters, so many Texas remodelers recommend a softener loop or point-of-use treatment as part of the project.

Texas has the second-newest housing stock in the nation (median age 28 years, NAHB/2024 ACS), so most remodels here are value upgrades: replacing builder-grade tubs and cultured-marble vanities, converting tubs to walk-in showers (about $3,000 on average, per Angi 2026), and adding storage. Plumbing is usually sound, which keeps budgets closer to the finish-focused end of the range.

If your home predates the 1970s — common in inner-loop Houston, central Dallas, and older San Antonio neighborhoods — have the contractor inspect supply and drain lines. Galvanized steel pipe common in 1940s–60s construction lasts about 40–50 years (Roto-Rooter) and cast-iron drains 50–60 years (InterNACHI), so original lines are past design life and cheaper to replace while walls are open.

Texas's large retiree population makes aging-in-place upgrades common. A walk-in tub averages about $13,100 installed (HomeAdvisor 2025); a full universal-design remodel averages $42,183 (Zonda Cost vs. Value 2025). A curbless shower with grab bars and a bench often achieves similar safety for far less.
