Will a restaurant bathroom in Al Shafa really need waterproofing work, and what does it usually cost? Al Shafa sits at 24.7969, 46.6401, about 9.9 km from the centre of Riyadh, with an approximate radius of 3 km. The area is largely commercial, with shops and offices, so many food-service premises share heavy daily use, frequent cleaning and constant floor traffic. Bathroom waterproofing for this kind of space is typically priced at SAR 15–40 per m², and the exact figure depends on the size of the floor and the condition of the existing layers.

Our inspection begins with a walk through the room to note the floor falls, the drains and any visible cracks or staining along the wall base. The technician then checks the surface for soft spots, hollow sounds and areas where old sealant has lifted. Where cracks are present, crack injection is quoted at SAR 40–125 per metre, and epoxy coating at SAR 35–95 per m² is one option for sealing the floor. Spray foam at SAR 20–45 per m² and bitumen membrane at SAR 15–35 per m² are alternatives that may suit different floor conditions. The inspector records measurements and photographs so the owner can compare options before any work starts.

Before the visit, please clear the bathroom floor and remove loose fittings where possible, so the technician can reach the wall base and drain area. Note any leaks, damp patches or past repairs you already know about, and have the approximate floor area in square metres ready, since the quote is calculated per m². If the room sits beside a kitchen or storage area that has also been affected, mention it, because the inspection can then cover the wider area in one visit. Having these details ready helps the inspection run smoothly and gives you a clearer picture of the work and its cost.

For restaurants, visits are planned outside service hours and recorded for the premises file.
