Bathroom Remodeling in Dallas, TX

The bathrooms in Dallas's classic neighborhoods tell you exactly when the house was built. A 1920s home in the M-Streets or Lakewood typically has one original bath — tucked off a hall, small, and often the only full bath for the whole house. A Dallas bathroom remodel is usually one of two projects: reviving that cramped original into something functional and beautiful, or carving a real primary suite out of space the original plan never dedicated to one.

Working with the original house

In the pre-war bungalows and Tudors of Winnetka Heights, Junius Heights, and Greenland Hills, the constraint is space and the opportunity is under the floor. Because these homes are pier-and-beam, re-routing a toilet drain, moving a vanity, or adding a second bath is far less invasive than on a slab — the crawlspace gives the plumber room to re-run supply and waste lines with proper fall. Expanding into a closet or a neighboring room to build a walk-in shower, a double vanity, or a freestanding tub is where the real gains happen. On mid-century homes in Preston Hollow and Lake Highlands, the same moves play out on a slab, where relocating drains means cutting and re-pouring concrete and settling the layout before anything is set.

Waterproofing is the whole job

A bathroom is the one room built to get wet every day, and in an older Dallas house — where a century of settlement on expansive clay can leave floors out of level — getting the water management right matters more than any finish. That means a properly sloped and tested shower pan, the right backer board and waterproofing membrane behind the tile, sealed penetrations, and exhaust ventilation ducted to the exterior so moisture leaves the house instead of feeding mold in original framing. Tile that looks flawless over a shortcut waterproofing job is the most common way a bathroom remodel fails a few years later.

The trades and the permit path

Bathroom work is plumbing and electrical work, handled by the state-licensed trades: re-piped supply and drain lines, GFCI-protected circuits, proper lighting and ventilation. It's permitted through Dallas's Planning & Development Department on the DallasNow portal — the Accela system that replaced the city's POSSE and ProjectDox platforms in May 2025 — and Dallas requires an active general contractor registration on file before it will issue the permit or schedule inspections, unless the homeowner files an Exemption to do the work on their own home. Interior bathroom work generally stays clear of historic-district review as long as the exterior is untouched.
