What a bathroom remodel costs in Dallas, and the choices that move the number

The range, and why it is so wide

On our website we cite a range of about $5,000 for a powder room up to $30,000 or more for a full primary bathroom redesign. Where your project lands depends mostly on four things: the size and type of the room, whether the plumbing stays where it is, how much tile goes in and how complex it is, and whether the cabinets and fixtures are stock or custom. Hidden damage behind the old shower is the wild card, and it is the one nobody can price until the walls are open.

At Spire Construction we remodel bathrooms across the eastern side of the Dallas metroplex, and the number one surprise for homeowners is not the total. It is how much of the total is labor and preparation that never shows in the finished photos. This guide walks through every factor we weigh when we write an estimate, so you can see which ones you control before anyone gives you a number.

Powder room, hall bath, primary suite: three different jobs

A powder room has a toilet, a sink and maybe a mirror and light. There is no shower, no waterproofing and very little tile, so the work is mostly a vanity, a toilet, flooring, paint and lighting. That is why it sits at the bottom of the range.

A hall or secondary bath usually has a tub with a tile surround. Keeping the tub and retiling the walls is one price; tearing the tub out and building a walk-in shower is another, because now you are building a waterproofed shower floor and changing the drain.

A primary bath often combines a separate shower and tub, double vanities, a toilet room and larger tile areas. More square footage of tile, more plumbing fixtures, glass enclosures and lighting all multiply. A primary bath that also changes its layout is where projects pass the top of the published range.

What actually moves the number

When we price a bathroom, these are the line items that swing the total most. Some are choices; some are conditions of the house that we can only estimate until demolition.

• Moving plumbing. Many homes in our area sit on a concrete slab, so relocating a toilet or shower drain means cutting and patching concrete, not just moving a pipe under a floor.
• Tub to shower conversions. A walk-in shower needs a properly sloped, waterproofed floor, a new drain location and usually more tile than the tub surround it replaces.
• Tile quantity and pattern. Floor-to-ceiling tile, small mosaics, niches, benches and patterns that need precise layout all add labor hours, which often cost more than the tile itself.
• Stock versus custom. Our bathroom page notes that cost depends on size, finishes and whether components are custom or stock. A custom vanity or a frameless glass enclosure built to measure costs more than a standard size.
• Fixtures and finishes. Valves, shower systems, faucets and lighting range widely. A body spray system needs different plumbing than a single showerhead.
• Ventilation and electrical. Adding an exhaust fan vented outside, new lighting circuits, heated floors or outlets near a vanity means electrical work by a licensed electrician.
• What is behind the walls. Rotted subfloor, old leaks, mold or outdated pipes found at demolition get repaired before the new bathroom goes in.

Older houses carry costs a newer one does not

If your house was built before 1978, any paid work that disturbs painted surfaces falls under the EPA's lead-safe Renovation, Repair and Painting rule, which requires certified firms and specific work practices. That adds containment, cleanup and time, and it is not optional for the contractor.

Older bathrooms also tend to hide the expensive surprises. Original showers were often built with waterproofing that has long since failed, and we regularly find soft subfloor or framing that has been wet for years. Galvanized supply pipes and aging drain lines are common in older homes, and when the wall is open, replacing them is far cheaper than doing it later. A good estimate names these possibilities up front and explains how they will be priced if found, rather than pretending they will not happen.

If you suspect the old shower is already leaking, read our guide on signs a tile shower is leaking behind the walls before you set a budget, because a leak changes the scope.

Where your money does the most work

If the budget is tight, spend on what you cannot easily change later and save on what you can. Plumbing, waterproofing and the shower valve live inside the wall for decades; paint, mirrors, light fixtures and hardware can be upgraded in an afternoon. Our own planning advice puts the plumbing system and quality fixtures at the top of the priority list for that reason.

Keeping the toilet, sink and shower drain where they are is the single biggest saving available in most bathrooms. A larger format tile on the walls means fewer grout lines and less labor than a small mosaic, and a mosaic used only on the shower floor or as an accent gives the look without tiling every surface with it. Choosing a standard size vanity, a standard tub and a semi-frameless glass door instead of custom sizes can also bring the total down without changing how the room works.

• Keep fixtures in their current locations when the layout already works.
• Put the budget into waterproofing, valves and plumbing first.
• Use larger tiles for big areas and save detailed tile for accents.
• Choose standard sizes for vanities, tubs and glass where you can.
• Make every selection before demolition so nothing waits on a decision.

Permits, inspections and paperwork

Cosmetic updates are one thing, but once plumbing, electrical or walls change, a permit is usually required, and the City of Dallas, for one, issues remodel permits only to registered contractors. The permit fee itself is a modest part of the total, but plan review and inspections affect the schedule. We cover the details city by city in our guide on whether you need a permit to remodel.

A permit protects you more than it protects the contractor. An inspector checks the plumbing and electrical before they are buried in tile, and a buyer's inspector years from now may ask whether the work was permitted.

How budgets slip once the work starts

Most bathroom overruns we are asked to fix were not caused by the original price. They came from decisions made after demolition. A homeowner sees the open wall and decides to add a niche, move the shower valve to the other side or upgrade to a larger glass panel. Each change is reasonable on its own, and each one adds labor, material and days to the schedule.

The second cause is selections made late. If the tile is not chosen when demolition begins, the crew either waits or moves on to another job and comes back later, and the schedule stretches. Special-order vanities and glass enclosures that are measured after tile is set also take time to arrive. The third cause is living without a working bathroom for longer than planned, which pushes some families toward rushing decisions they later regret.

The fix is simple and a little boring: finish the decisions before the first tile comes off the wall, ask for every change in writing with its price, and agree in advance on how any rot or leak found during demolition will be priced. When those three things are in place, the number you sign is very close to the number you pay.

How to read a bathroom estimate

Line up what is included before you compare totals. A low bid that leaves out demolition and disposal, waterproofing details, the exhaust fan, electrical work or the glass enclosure is not a low bid. Look for allowances for tile, fixtures and vanity, and check those allowances against what you actually plan to buy. If a bid allows a small amount for tile and you have chosen a stone mosaic, the real number is higher.

Ask each contractor how the shower will be waterproofed, what happens if rot is found, and who will be on site day to day. We wrote a longer guide on comparing remodel bids that do not match that applies directly to bathrooms.

• Demolition, disposal and protection of the rest of the house
• Waterproofing method for the shower walls and floor
• Plumbing and electrical scope, including the exhaust fan
• Allowances for tile, vanity, fixtures and glass
• How hidden damage is handled and priced
• Permit, inspections and final cleanup

Getting a real number for your bathroom

Our process starts with a free consultation at the house. We look at the bathroom, the plumbing access, the age of the home and any signs of past leaks, and we listen to what you want the room to do. If you are working with a designer we price their plan; if not, we can connect you with designers we work with.

From there we outline a timeline and budget and list the decisions you need to make: tile, vanity, fixtures, glass and lighting. You get an upfront written estimate before construction starts. Once work begins, the site is cleaned at the end of each day, you hear from us as the job moves along, and we finish with a final walkthrough together. We have been doing this in Richardson and the surrounding cities since 2017, and the owners have worked together since 2000, so the estimate you get reflects a lot of bathrooms opened up and rebuilt.
