Toto Bathroom Remodeling: The Dallas Owner’s Guide

A Toto-focused bathroom remodel in Dallas typically runs $9,000 to $28,000 installed, depending on whether you’re swapping a single fixture and its surrounding tile or rebuilding the entire wet area down to the studs. Most homeowners call us when a Toto toilet, washlet, or tub is still in fine working order, but the wall around it has failed; rotted subfloor, cracked tile, a shower pan that’s been leaking into the room below. We carry Toto-compatible trim, flanges, supply connections, and mounting hardware on our trucks, and we install Toto fixtures from homeowner-provided or trade-sourced orders every week.

Which Toto Models This Applies To

We work with the full Toto range common in Dallas homes: the Drake, Ultramax, and Nexus toilet lines; the Washlet C-series and S-series bidet seats; and Toto tubs and shower bases including the Soiree and Supreme models. Toto is not a one-size-fits-all manufacturer, and the most common mistake we see is a homeowner ordering a replacement part based on the model name alone. Toto stamps a four-digit or five-digit model code on every fixture, usually inside the tank for toilets, under the rim for tubs, and on a rating sticker on the base. That code matters. A Drake CST744E uses different internals than a Drake CST746CE, and the fill valves, flush valves, and seats are not interchangeable across every sub-model. When a part is discontinued, Toto’s OEM replacement is sometimes a superseded part number, which is why we verify the fixture code before ordering anything. For older Dallas homes with original Toto fixtures from the 1990s and early 2000s, aftermarket flush valves and gaskets are often the only practical option, and we source those from suppliers who test for fit before shipping. Penhallow Remodeling Dallas is an independent remodeling contractor, not affiliated with Toto, so we’re free to recommend the part that actually fits instead of the one corporate inventory wants moved.

Signs Your Toto Bathroom Is Failing

• Water staining on the ceiling below the bathroom. This is the one that sends people to the phone first. It usually means the Toto tub or shower pan gasket has been seeping for months, and the subfloor has already started to rot. By the time the stain shows, the repair is no longer caulk-and-paint; it’s a remodel.
• Tile cracking horizontally along the lower wall. In Dallas’s clay-heavy soil, slabs and foundations move seasonally. A long horizontal crack near the tub lip or shower base often means the wall has shifted and the waterproofing membrane behind the tile has torn. Grout alone won’t fix this.
• The Toto toilet rocks slightly when you sit. A rocking toilet is rarely the toilet’s fault. It usually means the flange beneath it has cracked or the subfloor has softened. Left alone, the wax seal breaks, and water seeps into the floor with every flush.
• Caulk that keeps pulling away from the shower base. If you’ve re-caulked twice in a year and it keeps separating, the shower base or tub is flexing. The structural support beneath it is failing. New caulk is a bandage, not a repair.
• A persistent musty smell you can’t place. That’s the smell of moisture trapped behind a wall or under a floor. In a Dallas summer with 100-degree days and high humidity, a small leak becomes a mold colony faster than most homeowners expect.

Replacement Cost & What’s Included

A Toto-specific bathroom remodel in Dallas runs $9,000 to $28,000, and here’s what moves the number. A straightforward job (new Toto toilet, new vanity, new tile floor, keep the layout) lands near the bottom of that range. A full gut-out with a new Toto tub, custom shower pan, cement board substrate replacement (the moisture-resistant layer behind your tile), and updated plumbing rough-in pushes toward the top. Every quote includes the tear-out, disposal, all materials, the fixture installation, and our workmanship warranty in writing. The 365-Day Done Right Promise applies to every Toto remodel we do. If something fails inside the guarantee period, we come back and fix it at no charge. No re-inspection fee, no service call. The number we hand you before we pick up a tool is the number on the invoice.

DIY or Call Us?

You can safely handle a few things. Inspect the Toto fixture code so you know exactly what you have. Check for visible water staining. Tighten a loose tank bolt if the toilet isn’t leaking at the base. That’s about where the safe line sits. Replacing a Toto tub or shower base means cutting into walls, pulling old substrate, and discovering whatever has been hiding behind the tile for years. In a Dallas home built before 1985, that sometimes means dealing with wet drywall, bad previous patches, or plumbing supply lines that were not done to current code. If the shower pan or tub has failed, the water damage is always bigger than what you can see from the outside. Call (940) 204-5368 and we’ll take a look, tell you what we find, and hand you a written number before any work starts.
