Showers, Vanities, and Tile Built to Stay Dry

A toilet needs 15 inches from its centerline to the nearest wall, a shower interior measures at least 30 by 30 inches, and an exhaust fan moves 50 cfm outdoors: those three figures from the residential code shape every bathroom remodeling plan Campbells Carpentry LLC draws up in Warrenton, MO, Wentzville, and Innsbrook. The work includes tub-to-shower conversions, vanity and tile work, layout changes, walk-in accessible baths, half-bath refreshes, and the waterproofing prep behind each.


Because we are an owner-operated shop, you talk directly with the carpenter who measures your bathroom, orders the cement board, and sets the trim. Honest recommendations mean telling you when a refresh will do instead of a gut job, and every estimate is free. Over 5+ years we have kept one habit: doing what we say we will do, with hands-on oversight of every licensed plumber and electrician on the job. Request an estimate on our contact page.

Complete Bathroom Remodels We Handle

Tub-to-Shower Conversions

Pulling a tub and building a walk-in shower in its place is a change many homeowners ask for first. We frame the curb or curbless pan, hang backer board, prep for tile, and coordinate the plumber for the valve and drain relocation.

Vanity and Cabinet Installation

Vanities carry real weight once a stone top, sink, and loaded drawers land on them. We anchor each cabinet into studs, scribe it to out-of-square walls, hang the mirror and medicine cabinet, and add linen towers where the floor plan allows.

Tile and Waterproofing Prep

Tile is only as good as what sits behind it. We hang cement board instead of green board in wet areas, tape the seams, slope the pan, and carry a non-absorbent surface to 6 feet above the floor at every tub and shower.

Bathroom Layout Changes

Moving a toilet, widening a doorway, or stealing a closet to enlarge the shower changes how a small bath feels. We rework the framing, keep 21 inches clear in front of the toilet, and line up new drain locations with the plumber.

Accessible and Walk-In Bathrooms

Aging in place starts with a bathroom that works without a step. We build curbless showers with a 36-by-36-inch interior, add blocking in the walls for grab bars, widen doors, and set comfort-height toilets and vanities that a wheelchair can roll under.

Half-Bath and Powder Room Updates

Small rooms reward careful work because every joint sits at eye level. We swap a pedestal for a compact vanity, add wainscoting or a tile accent wall, schedule the fixture swap, and refresh the door, casing, and baseboard in a few days.

Why Choose Us for Bathroom Remodeling

Water Stays Where It Belongs

Leaks show up months later as a stain on the drywall downstairs. We slope pans, flood-test them before tile, seal every seam in the backer board, and keep absorbent drywall out of the wet zone so the finish you paid for lasts.

Shortest Possible Downtime

Losing your only full bath is a real hardship, so we plan around it. Demolition waits until materials are on site, the toilet goes back in as soon as the floor allows, and we tell you the exact days the shower is unavailable.

Vents That Reach Outside

A fan that dumps 50 cfm of steam into the attic grows mold above your head. We plan every exhaust duct to a roof or wall cap, keep the run short, and it gets checked at inspection before the walls close.

Tile Lines That Run True

Grout lines that wander 1/8 in. are visible from the doorway forever. We lay out each wall from the center, check the pan for square before the first tile, and set niches and trim pieces to land on full tiles instead of slivers.

Built for the Next Owner Too

Midrange bath remodels in our region returned 76.8% of their cost in the 2025 Cost vs Value report. We steer you toward layouts, fixtures, and finishes that hold that value, and away from choices that date a bathroom within a few years.

Every Trade, One Contact

You never chase a plumber or an electrician. We bring in licensed trades for the valve, drain, GFCI receptacles, and fan circuit, schedule them around our framing and tile work, and stay on site so every hand-off happens on the day it should.

Dry Walls, True Tile, and a Bath You Can Trust

A bathroom gets used more times a day than any other room in the house, and it is the one room where a shortcut shows up as a soft spot in the floor a year later. Campbells Carpentry LLC builds bathrooms in Warrenton, MO, and nearby towns with cement board behind the tile, ducts that reach daylight, and plumbers and electricians scheduled around our own work. Nobody is going to rush you into a decision; look over the estimate, ask about materials, and compare it with anyone you like. When you are ready to talk about a shower conversion, a new vanity, or an accessible layout, request your free estimate on our contact page.

Frequently Asked Questions

  • How long does a bathroom remodel take?

    A standard bathroom takes 3 to 6 weeks of construction, or 6 to 10 weeks once design and permits are counted. Campbells Carpentry LLC gives Warrenton, MO homeowners a dated schedule before demolition, and a simple refresh wraps up in 2 to 3 weeks.

  • What do you do first when remodeling a bathroom?

    Settle the layout and pick every fixture before anyone swings a hammer, because the tub, vanity, and toilet dimensions dictate where the plumber roughs in the drains. Ordering long-lead items such as tile, glass, and the vanity top comes next, then demolition.

  • What are common mistakes to avoid when renovating a bathroom?

    Skimping on waterproofing, venting the fan into the attic, and choosing a shower smaller than 30 by 30 inches top the list. Forgetting blocking for grab bars, storage for towels, and enough light at the mirror round out the regrets we hear most.

  • Do I need an exhaust fan in a bathroom with a window?

    The IRC allows a window that opens in place of a fan, but a fan is the better choice in practice. Nobody opens a window in January, and a 50 cfm fan clears steam before it soaks into drywall and grout.

  • Does a bathroom exhaust fan need to vent outside?

    Yes, the IRC requires bath exhaust to terminate outdoors, never into an attic, soffit cavity, or crawlspace. Warm, humid air released inside the structure condenses on framing and insulation, which is why inspectors check the duct run at the open-wall stage before drywall.

  • Does a half bath need an exhaust fan?

    Only if it has no operable window, under the residential code, though we recommend one in most powder rooms anyway. Odor control matters more than moisture there, and a quiet unit on a timer switch costs little next to the tile.

  • What happens if I remodel my bathroom without a permit?

    Unpermitted plumbing or electrical work can stall a sale, complicate insurance claims, and force you to open finished walls. Campbells Carpentry LLC has spent 5+ years building to what Warrenton, MO inspectors check, so permits are part of the plan we walk you through.

  • Are one-day bathroom remodels worth it?

    Seldom for an older bath, because most one-day products are acrylic liners glued over the old tub and surround, trapping moisture and hiding damage instead of fixing it. A tub-to-shower conversion takes longer but replaces the backer, waterproofing, and plumbing you cannot see.
