How Much Does a Bathroom Remodel Cost? Real Numbers by Scope

A bathroom remodel costs $8,000 to $80,000 depending on the room. A powder room runs $8,000 to $15,000. A guest or hall bath runs $18,000 to $35,000. A primary bathroom runs $40,000 to $80,000. The cost driver that separates tiers is not size, it is wet area: how much tiled, waterproofed surface the job creates.

Bathrooms cost more per square foot than kitchens. A 40 square foot bathroom can cost as much as a 200 square foot kitchen refresh, because nearly every trade works in that small room and because water makes mistakes expensive.

Cost by room type

Why wet area drives the price

A powder room has no shower. That single fact removes waterproofing, tile surround, shower valve, glass, and drain work, which is why it costs a third of a full bath at similar finish level.

The moment a job includes a shower, it includes:

• Waterproofing membrane over the substrate, correctly lapped and sealed
• Sloped mortar bed to the drain
• Tile surround, priced by square foot of wall, not floor
• Shower valve and rough-in, which is inside the wall and cannot be changed later without demolition
• Glass, typically $1,200 to $3,500 for frameless

Waterproofing is the line item homeowners cut and the one that causes failures. A shower that leaks behind tile does not announce itself for two years, and then the repair is the entire bathroom plus the ceiling below it.

Note that labor is roughly 35 to 40 percent of a bathroom, higher than a kitchen’s 22 percent. Small room, many trades, tight sequencing.

What pushes a bathroom into the next tier

Moving the toilet. The drain is the constraint. A toilet drain needs specific slope and venting, and relocating it in a home with a slab foundation means cutting concrete. Budget $1,500 to $4,000.

Converting tub to shower. Common in primary bathrooms and generally worth it for daily use, though real estate advice varies if it leaves the home with no tub at all. Cost depends on drain relocation and whether the opening changes.

Curbless or barrier-free showers. Increasingly requested for aging in place. Requires recessing the subfloor or building up the entire floor, so the cost is structural, not cosmetic. Add $3,000 to $8,000.

Heated floors. Electric mats add $1,200 to $3,000 installed on a typical bathroom and require a dedicated circuit and thermostat.

Double vanity in a single vanity space. Often requires moving a supply line and drain, and sometimes a wall.

Where you should and should not economize

Worth the money:

• Waterproofing, always
• The shower valve, because it lives inside the wall
• Exhaust ventilation sized correctly for the room, which prevents mold
• The vanity, since it takes daily abuse and cheap boxes swell

Reasonable places to save:

• Tile selection, where a well-chosen porcelain at $4 per square foot can outperform a poorly chosen stone at $14
• Keeping fixtures in place
• Standard shower size rather than custom glass dimensions
• A quality stock vanity instead of custom millwork, which is where our bathroom vanities in Maryland selection tends to pay off

Maryland and Montgomery County specifics

Bathroom projects here run 15 to 25 percent above national averages. Two local factors matter:

Older housing stock. Homes in Bethesda, Silver Spring, Takoma Park, and Kensington built before 1970 frequently have galvanized supply lines, cast iron drains, or original subfloor damage discovered at demolition. We budget contingency for this rather than discovering it as a change order.

Permits. Montgomery County requires permits for plumbing and electrical work in bathrooms. Ventilation and GFCI protection are inspected. Verify current requirements with the Montgomery County Department of Permitting Services.

How long it takes

A guest bathroom typically takes 3 to 5 weeks of active work. A primary bathroom takes 5 to 8 weeks. Add 3 to 6 weeks before that for design, selections, and material lead times, longer if tile or vanities are special order.

The schedule risk in bathrooms is almost always tile and glass. Glass cannot be measured until the tile is set, and fabrication takes 1 to 2 weeks after templating. Plan for it rather than being surprised by it.

Frequently asked questions

How much does a bathroom remodel cost in Maryland?

A bathroom remodel in Maryland costs $8,000 to $80,000 depending on room type. Powder rooms run $8,000 to $15,000, guest bathrooms $18,000 to $35,000, and primary bathrooms $40,000 to $80,000. Montgomery County projects run 15 to 25 percent above national averages.

Why do bathrooms cost more per square foot than kitchens?

Bathrooms concentrate plumbing, electrical, waterproofing, tile, and glass into a small room, so fixed costs spread across less area. Labor is typically 35 to 40 percent of a bathroom budget compared with about 22 percent for a kitchen.

What is the most expensive part of a bathroom remodel?

Labor is the largest single line item in most bathroom remodels, typically $9,000 to $12,000 on a guest bathroom. Tile installation and waterproofing account for much of that because they are time-intensive and require skilled work.

Can I remodel a bathroom for $10,000?

A powder room remodel is achievable near $10,000. A full bathroom with a shower is generally not, because waterproofing, tile, glass, and plumbing fixtures alone approach that figure before labor. Refinishing rather than replacing a tub and keeping fixtures in place is the realistic path to a low-budget refresh.

How long does a bathroom remodel take?

A guest bathroom takes 3 to 5 weeks of active construction and a primary bathroom 5 to 8 weeks, plus 3 to 6 weeks beforehand for design and material lead times. Shower glass adds 1 to 2 weeks after tile is complete because it cannot be templated earlier.
