Walk-in showers and bathroom remodels in Dallas, TX: costs and rules

Dallas price ranges for walk-in showers

The table uses Angi's 2026 Dallas pages. Angi starts from national averages and adjusts them with local price data, so use these to sanity check bids, not to replace them^[1].

Dallas project	Most pay	Average
Walk-in shower, professionally installed	$6,186 to $12,372	$9,279[1]
Shower remodel (existing shower)	$2,062 to $9,279	$7,217[4]
Tub to shower conversion	$1,547 to $8,248	$3,093[2]
Whole bathroom remodel	$6,380 to $17,216	$11,582[3]

A few line items from the same pages help explain the spread:

• New plumbing for a shower runs $1,550 to $3,610^[4].
• Labor is 40% to 60% of a shower remodel, about $2,900 to $4,300^[4].
• Swapping a tub for a small shower stall costs $1,200 to $3,200, while a large shower can top $5,000^[2].
• Conversion crews in Dallas charge $60 to $95 per hour per worker^[2], and remodelers $50 to $100 per hour^[3].

The national picture is in our walk-in shower cost guide and tub to shower conversion cost guide.

When Dallas requires a permit

Dallas starts from a broad rule. No one may build, alter, repair, replace, install or convert a structure or its building service equipment without first getting a master permit from the building official^[5]. The exceptions are listed in Chapter 52, Section 301(b) of the Dallas City Code^[5].

Two items on the city's short list of exemptions matter for bathrooms^[5]:

• Stopping a leak in a pipe, drain or fixture, as long as no valve, pipe or fixture is replaced or rearranged.
• Nonstructural interior remodeling of a one or two family home that does not add floor area or change exterior doors or windows.

The second one sounds like it covers a shower remodel, but the plumbing is the catch. The city's general repair scope form, used for no-permit repair work, says that scope cannot include adding, altering or relocating water supply, sewer, drainage, waste or vent piping, and cannot include removing any wall or part of a wall^[6]. If an inspector finds work beyond that scope, the result can be a stop work order, amended permits and added fees^[6].

State law points the same way. Texas cities over 5,000 people must require a permit before plumbing, except for repairing leaks and replacing faucets, ballcocks, water control valves, disposals and toilets^[8]. A new shower valve, drain or pan is not on that list.

In short: retiling around an existing shower may fit Dallas's no-permit list. Replacing a tub with a walk-in shower, moving a drain, or removing a wall needs permits. Call Dallas Building Inspection at the Oak Cliff Municipal Center, 320 E. Jefferson Blvd., if you are unsure^[5].

Licensing: plumbers, contractors and homeowners

Plumbers. In Texas, plumbing licenses come from the Texas State Board of Plumbing Examiners (TSBPE), which has a public license search^[9]. Dallas says any plumbing contractor working on your home needs that state license, even when the work itself does not need a permit^[5]. A plumbing contractor must also register with any city that requires it before working there^[8].

General remodelers. Dallas says a license is not required for general building work on your own property^[5]. Contractors pulling a building permit register with the city, which is why the homeowner exemption is described as an exemption from "registration as a contractor"^[7].

Homeowners. A homeowner who owns, occupies and has homesteaded the house may do any kind of plumbing work there^[5]. Dallas's homeowner permit comes with an affidavit^[7]:

• You will do the work yourself and no one will be paid to help with any part of it.
• You will meet the Dallas codes and get every required inspection approved before using the new work.
• If you cannot, you agree to hire a properly licensed contractor to finish.

The affidavit is signed in front of city staff or notarized^[7].

What Dallas soil means for a shower project

Dallas has very active clay soil. By our calculation from USDA soil survey data, about 70% of rated soil area in Dallas County has high or very high shrink-swell potential^[11]. Clay like that swells when wet and shrinks when dry.

Almost every house here sits on a concrete slab. In 2024, 97.9% of new single-family homes started in the West South Central states were built on slabs^[13]. That puts the shower drain under the concrete, in that clay. Two things follow:

• A water leak under the slab is a foundation issue, not only a plumbing issue. The Foundation Performance Association lists leaking sewer or water lines as a cause of moisture change that can move foundations on expansive soil^[12]. If the old tub area shows signs of a slow leak, have it found and fixed before the new shower goes in.
• Moving the drain means opening the slab. A walk-in shower that keeps the tub's drain location costs less. A center drain, a linear drain against the far wall, or a curbless floor usually means cutting and re-pouring a section of slab. Ask that the drain line be pressure tested before the patch is poured, and that the quote says who is responsible for the patch.

A floor that already slopes or cracks near the bathroom is worth a look by a structural engineer before you invest in tile.

Dallas homes by age

The median Dallas home was built in 1981, and about 48% were built before 1980 (our arithmetic from Census data)^[10]. In bathrooms from the 1960s and 1970s, many contractors expect tile set on a thick mortar bed and price extra demolition time for it. Ask how the bid handles surprises found behind the wall.

When to call a pro

• Any shower valve, drain or pan work: a TSBPE-licensed plumber, and a Dallas permit unless you are doing your own homestead under a homeowner permit^[5][7].
• Removing a wall or widening the shower opening: a building permit, and a check of whether the wall is load bearing^[6].
• Signs of a slab leak or new cracks near the bathroom: a licensed plumber for a leak test, then a structural engineer if the floor has moved^[12].
• Moving the drain for a curbless or center-drain shower: get the slab cut, re-pour and drain test in the written quote.
