Prefill values are planning defaults for Nepal bathroom renovations, not quotations or guaranteed market prices. Tile brand, waterproofing system, sanitaryware model, city labour and hidden pipe damage can move totals substantially. Edit every rate before relying on the estimate.

Your estimate

A standard-finish bathroom renovation planning estimate from the dimensions and scope you selected.

Floor area (tiling basis): 35 sq. ft.
Wall tile area: 150 sq. ft.
Demolition / strip-out: NPR 3,325
Waterproofing: NPR 25,900
Floor tiles (supply + install): NPR 13,300
Wall tiles (supply + install): NPR 48,000
Sanitary fixtures: NPR 220,000
Plumbing rework package: NPR 55,000
Electrical / geyser points: NPR 28,000
Bathroom subtotal: NPR 393,525
12% contingency: NPR 47,223
Planning budget: NPR 440,748

Planning estimate only—not a quotation, BOQ or contract price. Defaults are not guaranteed market prices. Structural repairs, full wall rebuilds, imported sanitaryware beyond your fixture rate, false ceiling, vanity cabinetry, glass partitions, GST/VAT, design fees and mid-project upgrades are outside these lines unless you add them. Confirm rates with current local tile, waterproofing and plumbing contractors.

What this estimate assumes

Scope notes for a practical bathroom budget

No tile double counting. Floor tiles use length × width only. Wall tiles use perimeter × wall tile height − openings. Floor area is never added into wall area.
Waterproofing surface. When included, waterproofing = floor area + net wall tile surface (membrane under both), charged only on the waterproofing rate—not re-added as tile area.
Fixtures. Count WC, basin, shower set, mixer, mirror light, etc. as separate fixtures if you want item-level control; average rate × count is a planning shortcut.
Optional packages. Turn demolition, waterproofing, plumbing or electrical off when those scopes are already covered elsewhere or not required.

Formulas used

Floor area = L × W × bathrooms
Wall tile area = [2 × (L + W) × tile height − openings] × bathrooms
Waterproof area (if on) = floor area + wall tile area
Subtotal = demo + waterproof + floor tiles + wall tiles + fixtures + plumbing + electrical
Planning budget = subtotal × (1 + contingency%)
