A standard full bathroom remodel averages $12,000–$28,000 in 2026. Half baths run $5,000–$12,000. Master suite renovations with custom tile and premium fixtures range from $28,000–$60,000. Moving a toilet, sink, or shower drain requires opening floors and walls to reroute drain lines, work that adds $1,500–$5,000 per fixture before any aesthetic choices are made.

In a bathroom remodel, labor and plumbing fixtures together typically consume about half the budget before a single tile goes on the wall. The other half covers everything the homeowner usually spends the most time choosing: the vanity, the tile pattern, the fixtures, the shower enclosure. Both halves matter, but only one of them significantly changes based on layout decisions.
The decision to move or not move a drain line, toilet, or shower location is the primary variable that separates a $12,000 remodel from a $30,000 one in the same size bathroom. Everything else, tile grade, vanity style, fixture brand, adjusts cost at the margins.
Half baths run $5,000–$12,000. Full bathrooms average $12,000–$28,000. Master suite renovations with premium finishes run $28,000–$60,000. Moving any drain connection in any tier adds $1,500–$5,000 per fixture before aesthetic choices are factored in. Waterproofing the shower assembly is not optional: it's the work that determines whether the renovation lasts 20 years or 5.

Half bath / powder room ($5,000–$12,000): No shower or tub, just a toilet and vanity. Updates stay in place: new vanity cabinet and stone top, toilet replacement, updated faucet and lighting. No plumbing relocation. Timeline: 3–5 days for the visible work.
Standard full bath ($12,000–$28,000): Includes a tub/shower replacement in the same location. Typically: a prefabricated acrylic alcove unit or a custom-tiled shower in the existing footprint, new ceramic or porcelain floor tile, double vanity with stone countertop, updated lighting and fan. Timeline: 2–3 weeks.
Primary suite ($28,000–$60,000): Custom tile shower with zero-threshold entry, frameless glass enclosure, dual showerheads, freestanding soaking tub, heated tile floor, custom cabinetry, premium plumbing fixtures. Upgrading high-demand fixtures may require checking your water heater lifespan to ensure adequate hot water capacity. Timeline: 6–8 weeks.

The waterproofing line item is often the one that separates a remodel that lasts 15–20 years from one that fails in 5. At roughly 8% of a $15,000 project, it's a relatively small portion of the budget for work that determines the longevity of everything installed above it.
Tile and grout are not waterproof. Water passes through grout joints, and if there is no membrane between the grout and the substrate, moisture reaches the wall framing. Over years, that moisture causes rot, mold, and structural damage that costs far more to remediate than a properly installed waterproofing system costs upfront.
The TCNA Handbook, the industry standard for tile installation, specifies approved waterproofing systems for wet areas. Liquid-applied membranes (such as RedGard or equivalent) require a minimum of two coats with fiberglass mesh embedded at all corners and changes of plane. Sheet membrane systems (like WEDI or Schluter Kerdi) are applied to the substrate before tile and provide continuous coverage without the cure time of liquid systems.
Ask your contractor specifically which waterproofing system they're using and whether it meets TCNA standards. This is not a detail to leave unspecified.
A bathroom exhaust fan is required by the International Residential Code in all bathrooms without a window. Even in bathrooms with windows, a properly sized fan is necessary to control humidity after showering and prevent condensation from damaging painted surfaces and grout.
The IRC requires a minimum of 50 CFM for bathrooms under 100 square feet, or 1 CFM per square foot for larger spaces. The fan must exhaust to the exterior, not into the attic or a soffit. Venting into unconditioned attic space deposits moisture where it breeds mold in the insulation and sheathing.
If your existing fan vents into the attic, rerouting the duct to exterior is typically a straightforward addition to a bathroom remodel. Confirm this is part of your contractor's scope if you're doing a full renovation.

Asphalt shingles, metal panels, clay tile, and natural slate each fail for different reasons and on different timelines. Here's what actually determines how long each material lasts in real conditions.
Curling shingles, granules in the gutter, light through the attic, learn which warning signs mean a repair can buy you time and which mean the clock has already run out.
HVAC replacement runs $5,000–$14,000 for most homes in 2026. The price depends on system type, capacity, and ductwork condition, not just square footage. Here's what each decision costs.
