Custom Bathroom Remodeling | General Contractor Portland

Bathroom remodeling goes wrong out of sight, under old tile and above the ceiling, so we check the subfloor for rot and duct the fan outdoors. A fan venting into the attic leaves wet air up there all winter.

  • Tile or surround, priced both ways

This page covers bathroom remodels in Greater Portland houses, from a basic update of a small bath to a full gut with extensive tile, one room at a time.

It is for owners with a dated, soft-floored or badly vented bathroom. General Contractor Portland opens the floor to look for rot, sends the fan's air outdoors, and settles tile or a surround and any plumbing moves before the price is fixed.

The figure to keep: per bathroom, a small basic update starts at $13,000, a typical medium bath averages about $16,500, and a gut with extensive tile runs $27,500 to $38,500.

Why Does a Bathroom Vent Fan Matter So Much?

A bathroom vent fan matters because every shower puts water in the air, and a weak or attic-ducted fan lets it soak the ceiling and roof framing. We size each fan to the room and vent it outside.

  • Bathroom remodeling: shower with glossy pale blue-green tile on three walls, a recessed shelf, black fixtures and a small hexagon tile floor with a square drain
  • Fan ducted outdoors, never into the attic
  • Subfloor opened and checked for rot
  • Tile or surround, priced side by side
  • Rot checked before tile goes down
  • Fixed price per bath
  • A written update each week

What Decides Whether a New Bathroom Lasts?

Three things decide whether a new bathroom lasts: the air leaving it, the floor under it and its walls and pipes.

  • The Vent Fan and the Moisture You Cannot See

    Peeling ceiling paint and dark stains on the attic side of the roof boards point to a fan that is too weak or ducted into the attic.

    We size the fan to the room, run its duct to a cap outside and put it on a timer so it runs after the shower.

  • Subfloor and Rot Under Old Tile

    Small leaks around a toilet or tub soften the subfloor long before the tile shows it. In older Maine houses rot turns up often enough that we list it as a likely cost, not a surprise.

    Once the floor is open we cut out soft wood and lay a flat, stiff subfloor, because tile over a flexing floor cracks at the grout.

  • Tile or Surround, Moving Pipes, Septic

    Among finishes, tile swings a bath budget most: small mosaic takes hours of setting, large-format tile goes faster but needs a dead-flat wall, and a one-piece surround costs less.

    Moving a drain outweighs any finish choice. On septic, the HHE-200 form records the bedroom count the system was designed for, so a bath that arrives with a new bedroom must fit that design.

How to Remodel a Bathroom Without Covering Up Rot

  1. Bathroom remodeling first visit: two men seen from behind in a doorway, one in a gray shirt and one in a navy sweater, facing an older bathroom with pale green tile

    We look under, behind and above the room.

    We press the floor for give, check the attic over the ceiling and trace where the fan duct ends before pricing.

  2. Bathroom remodeling in progress: stripped bathroom with gray panel walls and taped seams, a white tub under a window, a floor drain and bare unfinished flooring

    One per-bath price, in writing.

    Tile or surround and any plumbing moves become a fixed price in a signed contract, and Maine's contract statute keeps your first check to a third of it.

  3. Bathroom remodeling final walkthrough: A man in a tan shirt and a woman in a gray sweater, seen from behind, facing a bathroom with a green tile tub wall

    Opened, repaired, finished, walked.

    Joe checks each stage before tile covers it, rot is priced in writing before the floor closes, and our 5-year written warranty begins at the final walkthrough.

When Does Bathroom Remodeling Need a Full Gut?

Bathroom remodeling needs a full gut when the floor is soft, the tile is cracked across its grout lines or the plumbing has to move, because patching over any of those only hides them.

It does not need one when the floor is solid and the layout works: a basic update at the $13,000 floor (a new vanity and toilet plus a fan ducted outside) sets a small bath right.

We would rather tell you a basic update is enough than sell a gut the room does not need.

  • Who usually needs a bathroom remodel?

    The people who usually need a bathroom remodel have a soft spot by the toilet, a fan that moves no air, a dated room before a sale or a plan to age in place.

  • Where in the house can a new bath go?

    A new bath can go wherever a drain reaches the main stack with enough slope, which is why bathrooms usually sit one above another, and a basement or an addition can take one too.

  • When is the right time to remodel a bath?

    The right time to remodel a bath is before a small leak becomes a rotted floor, and in a one-bath house, when you can shower elsewhere.

How Much Does Bathroom Remodeling Cost Per Bath?

Bathroom remodeling in Greater Portland costs $13,000 per bath at the floor for a small, basic update, and a medium bath usually lands near $16,500. Each figure is a per-bath average from many jobs, never a quote.

BathroomWhat it usually coversAverage per bath
Small, basic updatevanity, toilet, fan, floor$13,000 floor
Mediumtile floor, tub or shower, vanityabout $16,500, up to $22,000 to $24,000
Full gut, extensive tilestuds out, tiled shower and walls$27,500 to $38,500

Per-bathroom averages: two baths, two prices.

  • Why is a bathroom priced per bath?

    A bathroom is priced per bath because each room carries its own plumbing, fan, tile and floor, so two bathrooms are two prices.

  • What moves a bathroom price the most?

    Moving plumbing moves a bathroom price the most, then rot under the subfloor, the vent run, septic capacity and tile over a surround.

  • What does a bath inside an addition cost?

    A bath inside an addition costs more per square foot than the bedroom beside it, since plumbing and tile pack into a small floor, which pulls an addition above its $350 average.
