Primary Bathroom Remodel Cost in 2026: $12,000-$45,000

Primary bathrooms average 100-120 sq ft in newer homes, versus 40-60 sq ft for a standard bath. Labor and materials scale with every square foot - tile alone for a 120 sq ft primary bath at mid-range pricing runs $4,000-$8,000 versus $1,500-$3,000 for a smaller bathroom.

Most primary bath remodels include both a walk-in shower and a freestanding or jetted tub - a combination that runs $5,000-$18,000 just for these two elements. A custom tile shower with frameless glass adds $6,000-$10,000; a freestanding soaking tub adds $1,500-$6,000 for the fixture plus $500-$1,500 installation.

A 60-72 inch double vanity is standard in primary baths. Stock double vanities start at $800-$1,500 installed. Custom built-in cabinetry with his-and-hers sinks runs $4,000-$10,000. Adding a separate makeup vanity or built-in linen tower adds $800-$3,000.

Electric radiant floor heating is a popular upgrade in primary baths. Materials cost $300-$600 for a 100 sq ft floor; installation adds $500-$1,500 when done alongside a tile remodel (less disruptive than retrofitting). The thermostat adds another $150-$300.

Upgrading to a steam shower adds $2,000-$5,000 for the steam generator, waterproofing, and controls. A jetted or air-jet tub adds $1,000-$4,000 above a standard soaking tub. These features also require dedicated electrical circuits ($300-$600 each).

“Is this a fixed-price bid or a time-and-materials contract?”

Why this matters: Fixed-price bids protect you from runaway costs. Time-and-materials contracts can balloon if demo reveals hidden problems. For a primary bath remodel, push for a fixed price with a defined allowance for unforeseen conditions.

“What is your experience with large-format tile and stone installation?”

Why this matters: Large tiles (18x18 and up) require a perfectly flat substrate and specific adhesive. Inexperienced setters produce lippage (uneven edges) and cracked tiles. Ask to see photos of comparable tile jobs.

“How do you handle waterproofing in the shower, and what system do you use?”

Why this matters: Industry-leading systems include Schluter Kerdi, RedGard, and Wedi board. The materials cost $200-$600 more than basic felt paper, but the difference in leak prevention over 10-20 years is enormous.

“What permits will you pull, and are inspections included in your timeline?”

Why this matters: Primary bath remodels almost always require permits for plumbing and electrical. Inspections add 1-3 days to the schedule. Know this upfront so it doesn't surprise you.

“What is your subcontractor situation - are plumbing and electrical in-house or subbed out?”

Why this matters: When a GC subs out all the trades, markups stack up and coordination breaks down. Knowing who the subs are and whether the GC has worked with them before matters.
