Critical Bathroom Quality Factors

Waterproofing — Sika, BASF systems. 15-25 year service life if properly applied. Avoid cheap waterproofing.
Floor slope — minimum 1:50 toward drain. Critical to prevent puddling.
Ventilation — exhaust fan + window. Mandatory to prevent mold + humidity damage.
Plumbing pipes — PPRC for hot/cold supply (NOT PVC). UPVC for drainage.
Wall tiles to ceiling — wet areas should have tile to ceiling, not just shower zone.
Quality fittings — taps + showers from same brand (looks coordinated + warranty consistency).
Lighting — task lighting at mirror + general ceiling light + waterproof shower light.

FAQs

Total bathroom cost (master) for 10 marla?

Standard premium: Rs 4-7 Lac (Master/Toto sanitary, tiles, vanity, lighting). Luxury: Rs 10-20 Lac (Hansgrohe/Duravit, premium marble, designer lighting).

Walk-in shower vs shower stall?

Walk-in for premium feel + accessibility. Stall for water containment in small bathrooms. Walk-in needs proper floor slope + central drain.

Bathtub worth it?

Master bath in 10 marla+ — yes for resale + luxury feel. Smaller homes — skip, prioritize bigger shower. Freestanding tubs are premium statement pieces.
