Projekt 1Bathroom renovation
Bathroom quote calculator in Google Sheets and Excel
Room size in, materials, labour and a ready PDF quote out. Prices live on one tab, so the owner changes a rate once and every quote updates.



Problem
Co rozwiązuje
Renovation companies usually put every quote together by hand after a site visit: measure, look up tile and adhesive prices, add labour, add VAT. It is easy to end up a box short or with last year’s rate.
Najtrudniejsza część
Co musiało się zgadzać
Openings and rounding. Wall area must exclude doors and windows, and materials are sold by the box, not by the m². The sheet keeps exact areas for labour and rounded quantities for materials, so neither half of the quote is off.
