Why a Checklist, and What a Bathroom Costs in October 2026
A mid range bathroom remodel in the US runs about $70 to $250 per square foot all in, or roughly $8,000 to $25,000 for a standard 40 square foot bathroom in October 2026, based on published Angi and HomeAdvisor remodel cost data. Materials are typically 40 to 50 percent of that. The problem is never the big items: everyone remembers tile and a vanity. The problem is the forty small items around them, because a bathroom packs plumbing, electrical, waterproofing and finishes into the smallest room in the house, and every trade needs parts the others forgot. This checklist walks the room system by system, with quantities for a standard 5 by 8 foot bathroom with a tub shower, so you can build a shopping list and a budget that do not collapse on day three.
Tile, Backer and Waterproofing
| Item | Quantity for a 5x8 bath | October 2026 cost |
|---|---|---|
| Wall tile, tub surround (about 80 sq ft) | 88 to 95 sq ft with waste | $2 to $8 per sq ft, $175 to $760 |
| Floor tile (40 sq ft) | 44 to 46 sq ft with waste | $2 to $10 per sq ft, $90 to $460 |
| Cement backer board, 1/2 inch | 6 to 8 sheets, 3x5 ft | $12 to $18 per sheet |
| Waterproofing membrane or liquid | 1 kit or 1 gallon plus tape and corners | $150 to $450 total |
| Thinset mortar, modified | 2 to 3 bags, 50 lb | $18 to $35 per bag |
| Grout | 1 to 2 bags or boxes | $15 to $40 |
| Tile edge trim (Schluter type) | 3 to 5 sticks, 8 ft | $15 to $30 per stick |
| Shower niche, prefab | 1 | $50 to $120 |
| Caulk, silicone, color matched | 2 tubes | $10 to $16 per tube |
| Backer screws and seam tape | 1 box each | $25 to $45 combined |
The math behind the tile rows is simple: measure each surface, add 10 percent for cuts, more for diagonal layouts. Our Tile Calculator and Grout Calculator do it precisely for your room, including the way small tiles multiply grout consumption. Do not guess these two numbers: tile shortages mid job risk dye lot changes, and grout shortages risk a color shift exactly where the eye lands.
Plumbing Fixtures and Rough Parts
| Item | Budget range | Mid range |
|---|---|---|
| Tub or shower base | $250 to $600 | $600 to $1,500 |
| Shower valve and trim kit | $120 to $300 | $300 to $700 |
| Toilet | $150 to $300 | $300 to $700 |
| Vanity with top, 30 to 48 inch | $300 to $700 | $700 to $1,800 |
| Faucet | $60 to $150 | $150 to $400 |
| Wax ring, supply lines, angle stops | $25 to $60 total | Same. Buy new, always |
| Drain assemblies and P traps | $40 to $120 | $120 to $250 in metal finishes |
| Shower door or curtain rod | $30 curtain setup | $400 to $1,200 glass door |
Two rules save real money here. First, keep plumbing in its existing locations unless the layout truly fails: moving a drain or supply line adds $500 to $2,000 per fixture in labor and patching. Second, buy the valve and trim from the same brand and series. Shower valves are brand specific behind the wall, and the pretty trim kit from another line will not fit the rough valve your plumber installed.
The Rest of the Room
- Exhaust fan: $100 to $400, sized at least 1 CFM per square foot, vented outside. This is a moisture control device, not a luxury, and it protects everything else on this list.
- Lighting: vanity light $80 to $400, plus a damp rated ceiling or shower light $40 to $150. Put them on separate switches if the budget allows.
- Mirror or medicine cabinet: $80 to $600. Recessed cabinets need the wall opened between studs, so decide before drywall closes.
- Paint: one gallon of bathroom rated paint, $40 to $70, plus primer for new drywall. Ceiling paint too, while the room is empty.
- Drywall and patch materials: 2 to 4 sheets for a gut job at $12 to $18 each, joint compound, tape and corner bead $40 to $80.
- Flooring underlayment: uncoupling membrane for tile floors, $1.50 to $2.50 per square foot, or cement board if the budget is tight.
- Hardware: towel bars, toilet paper holder, robe hook, $60 to $250 the set. Buy them with the faucets so finishes match exactly.
- Access panels and shut offs: $15 to $40, and the cheapest future repair insurance in the building.
DIY Versus Pro: Where Homeowners Save Safely
Demolition is the great DIY savings in a bathroom: a careful homeowner with a dumpster can remove a standard bath in a weekend and save $500 to $1,500, keeping the plumbing capped by a plumber for an hour of labor if needed. Painting, mirror and hardware installation, and vanity setting on existing plumbing are also safe homeowner work. Tile setting is learnable and many first bathrooms come out well, but it is slow, and the waterproofing beneath it must be right, because that layer cannot be inspected once tile covers it. Plumbing moves, electrical work and glass door installation belong to licensed pros in most jurisdictions, for code and insurance reasons as much as skill. A realistic hybrid budget: homeowner does demo, paint and trim out, pros do rough in, waterproofing and tile, saving roughly a quarter of the labor bill without gambling on the layers that flood houses.
Sequence: Buy in This Order
Order long lead items first: vanity, tile, fixtures and glass are commonly 1 to 6 weeks out, and a remodel should never start demo until everything is on site or confirmed in a local warehouse. Check every tile box for the same lot number when it arrives, open one box of each fixture to confirm finish and completeness, and store the valve boxes where the plumber will find them on rough in day. Keep receipts and one extra box of each tile: returns of full boxes are easy within the window, and the spare box becomes priceless in year four when a single tile cracks. Run the quantities through the calculators linked above as you finalize each line, and your checklist becomes a budget, line by line, that a contractor can quote against directly.
Turning the Checklist Into a Budget Number
To turn this checklist into a working budget, price it in three passes. Pass one is the wet work: tile, backer, membrane, thinset, grout and trim from the first table, which for a standard bath totals roughly $700 to $2,200 depending on tile taste. Pass two is fixtures, from the second table, roughly $900 to $4,800 across the budget to mid range columns, with the vanity and shower glass doing most of the swinging. Pass three is the room itself: fan, lighting, mirror, paint, drywall and hardware, roughly $500 to $1,600. Add the three passes, then add 15 percent as a contingency you are not allowed to spend on upgrades in week one, because it belongs to whatever the walls are hiding: the rotted subfloor at the tub edge, the galvanized pipe that crumbles when touched, the junction box buried since 1974. Remodelers who open walls for a living will tell you the contingency is not pessimism, it is the most consistently accurate line in the whole estimate. Whatever is left at the end buys the good towels.
