Waterproofed, then beautiful

Bathroom Remodeling in Missoula, Montana

Tile showers, soaking tubs, double vanities and proper ventilation, built by carpenters who treat waterproofing as the job and the tile as the reward. Fixed-scope quotes and one crew from demo to the last bead of silicone.

A bathroom is the smallest room in the house and the easiest one to ruin. Water gets behind tile through a missed corner or an unsloped pan, sits in the framing for a few years, and turns a 1960s South Hills bathroom into a subfloor replacement. Constructive Brothers builds bathrooms from the framing out. We replace rotten joists and subfloor while the room is open, set a properly sloped pre-slope under the pan, and waterproof the shower with a Schluter Kerdi or comparable membrane system that gets flood-tested before a single tile goes up. Cement board or foam board goes on the walls, never green drywall behind tile, and every penetration is sealed.

Ventilation matters more in Missoula than most places because the house stays sealed through months of cold and smoke. We install a properly sized exhaust fan on a timer or humidity sensor, ducted outside with insulated pipe rather than dumped into the attic where it feeds mold. On older homes in the University District and Rattlesnake we can also fit a second bathroom into the footprint you have, often by borrowing a closet or a piece of a large bedroom, and we route the new plumbing so the drains still have the slope they need. Porcelain tile, LVP, quartz or solid-surface tops, and fixtures you can get parts for in ten years: we will help you choose materials that suit the house and the budget.

A full bathroom remodel in Missoula typically runs $22,000 to $45,000 for a hall bath and $40,000 to $75,000 for a primary bath with a tile shower and double vanity, with tile choice, plumbing relocation and the amount of hidden rot being the main drivers.

Why Us

Why Missoula Homeowners Choose Us for Bathroom Remodels

Flood-tested before tile

Every shower we build gets a membrane system, sealed corners and a 24-hour flood test before the tile goes on. If it is going to leak, we want to know while the fix costs an hour rather than after it has ruined the ceiling below.

Rot gets replaced

Older Missoula bathrooms usually hide soft subfloor around the toilet flange and tub. We open the floor, replace damaged joists and plywood, and set the new toilet on a flange at the correct height, so the room is solid before anything pretty goes in.

Ventilation that leaves the house

A fan that dumps into the attic rots the roof sheathing from below, and it is common in Missoula houses. We duct every exhaust fan outside through insulated pipe with a damper, sized to the room, and put it on a timer so it actually runs.

Tile set by carpenters who framed the walls

Straight tile needs flat, plumb walls, and our crew builds both. Large-format porcelain, 3x6 subway, hex mosaics on the floor and niches built into the studs all get laid out from the center so cuts land evenly at the corners.

Our Process

How a Bathroom Remodels Project Runs

Assess and design

We look at the existing plumbing, check the floor for rot, and talk through what you need: a tub for kids, or a second bath squeezed into an old closet.

Fixed-scope quote and selections

You get an itemized quote covering demo, framing repair, waterproofing, tile, fixtures and paint, with allowances for anything you have not picked yet. We order tile and fixtures before demo so nothing sits open waiting on a shipment.

Demo, plumbing and waterproofing

We gut the room, repair the structure, get plumbing and electrical roughed in and inspected, then build the shower pan and membrane and flood-test it for a full day.

Tile, fixtures and final

Tile goes on, then the vanity, toilet, fixtures, mirror, fan and trim. We grout, seal, silicone the changes of plane, and do the final inspection and walk-through with you.

FAQs

Bathroom Remodels Questions, Answered

How long does a bathroom remodel take?
A hall bath with the fixtures staying in the same spots takes two to three weeks on site. A primary bath with a custom tile shower, moved plumbing and a new layout runs four to six weeks. The flood test and the tile curing times are days we will not skip, because rushing a shower is how leaks start. Ordering tile and fixtures before demo keeps the room from sitting torn apart waiting on a delivery.
Can you add a second bathroom to my older Missoula home?
Usually. Many pre-war houses in the Northside and Westside have one bath for a family of five, and there is often room to carve a three-quarter bath out of a large closet or a rear porch. The limiting factors are drain routing, which needs slope back to the main stack, and venting. We check both before quoting so you know whether it is a $30,000 job or a $60,000 one.
Tile shower or a prefab fiberglass unit?
A one-piece fiberglass or acrylic unit costs less and has no grout to maintain, but it often will not fit through the doors of an older house and it looks like what it is. A tile shower costs more and takes longer, but it fits any space and lasts decades when waterproofed correctly. We build both and will give you honest numbers for each.
Do you handle the plumbing and electrical too?
Our carpenters do the demo, framing, waterproofing, tile, vanity and trim. Licensed plumbers and electricians we work with regularly handle the rough-in and final connections, and their work is inspected under the same permit. You still deal with one foreman and one schedule, and the plumber shows up when we say they will because we book them before demo starts.
