A master bath refresh ($32,000–$42,000) replaces tile, vanity, fixtures, glass, paint, and lighting without moving any wall or plumbing fixture. Schedule: 4–7 weeks. Best return for most homeowners. The visual transformation is dramatic; the cost containment is real.
A mid-range master bath gut ($46,000–$62,000) replaces all the above plus expands or relocates the shower, adds a freestanding tub, upgrades the vanity to double sink, and may rework the closet boundary. Schedule: 7–12 weeks. Plumbing relocation is the single most expensive line if you're moving the toilet or tub.
A premium master bath ($68,000–$110,000) reworks the layout entirely — new water closet, new tub niche, new shower with bench and multiple heads, custom vanity with under-mount lighting and integrated charging, radiant floor heat throughout, possibly a steam shower or sauna. Schedule: 14–20 weeks. Custom glass is on a 6–10 week leadtime. Custom vanities are 8–14 weeks.
Tile dominates the budget at 24–36% across all tiers. Standard porcelain ($12–$22/sf installed) keeps a refresh in budget. Large-format porcelain ($18–$32/sf) is the visual upgrade most homeowners actually want. Natural stone ($28–$58/sf) is the premium move that reads "high end" without being garish.
Glass enclosures separate the tiers as much as anything. Semi-frameless ($1,800–$2,800) is acceptable in a refresh. Frameless ($3,200–$4,800) is the mid-range standard. Full steam-tight frameless with custom-fab corner ($5,400–$9,800) is the premium signature.
Heated floors are the highest-ROI upgrade in any master bath. A 60–100 sf area runs $1,800–$3,800 installed and reads as luxury every single morning. Steam showers cost $4,800–$12,000 added and are used by under 30% of owners post-install. Make the steam shower decision based on actual planned use, not aspiration.
Vanity counters in a master typically run 6–10 linear feet. Quartz: $400–$1,200 in materials, $400–$800 installation. Natural stone: $800–$3,200 in materials, $400–$1,000 installation. Counter-to-counter slab match in a his-and-hers configuration is a $400–$1,200 fabrication line — invest there if your stone has visible movement.
Plumbing fixtures separate builder-grade from designer in the most visible way. Brizo, Kallista, Waterworks, and Watermark sit at $4,800–$12,000 for a complete master bath fixture set. Delta, Moen, Kohler quality lines sit at $1,400–$4,800. Both perform fine — the visual difference is real and the resale value attribution is small.
