Plan

Take before photos

Assess existing space

Measure room dimensions, note window and door placement, check structural elements.

Hire general contractor

Interview 3-5 licensed contractors. Check references, insurance, and past bathroom work.

Finalize budget

Break down costs: labor, materials, fixtures, tile, and contingency. Add 15-20% buffer.

Pull permits

Obtain required permits for plumbing, electrical, and structural work from local building department.

Select all materials

Choose tile, vanity, fixtures, lighting, paint colors, and accessories before demo starts.

Demo

Protect adjacent areas

Seal off bathroom with plastic sheeting. Cover floors and nearby furniture with drop cloths.

Remove all fixtures

Disconnect and remove toilet, vanity, tub/shower, mirrors, lighting, and accessories.

Demo tile and surfaces

Remove old floor tile, wall tile, backerboard, and damaged drywall. Expose studs.

Check structural integrity

Inspect exposed framing, subfloor, and joists for water damage, rot, or necessary repairs.

Rent dumpster or arrange disposal

Old tile, fixtures, and debris are heavy. Plan for 10-15 cubic yards of waste removal.

Rough Work

Plumbing rough-in

Relocate or install new supply lines, drain pipes, and vent stack for new layout.

Electrical rough-in

Run new wiring for lights, outlets, exhaust fan, and heated floors if planned.

Frame any new walls

Apply waterproof membrane

Paint on liquid membrane or install sheet membrane on all wet areas per manufacturer specs.

Waterproof corners and seams

Flood test shower pan

Plug drain, fill pan with 2-3 inches of water, wait 24-48 hours, check for leaks below.

Tile Work

Plan tile layout

Dry-lay tiles to minimize cuts, balance pattern, and determine starting point.

Install wall tile

Apply thinset mortar, set tiles with spacers, work in small sections from bottom up.

Install floor tile

Set floor tile with proper thinset, ensure slope to drain in shower, use anti-fracture membrane.

Grout all tile

Finish

Install light fixtures

Attach vanity lights, recessed lights, or pendant fixtures. Ensure GFCI protection near water.

Add accessories
