Bathroom waterproofing in Samtah starts with the site's position. The centre of Samtah sits about 61 m above sea level (SRTM open elevation data), and the town is about 22.6 km from the sea coast (OpenStreetMap). A technician checks how water is likely to move across and under the floor before quoting, because a bathroom that sits on higher ground drains differently from one in a low corner. The first checks are therefore the floor fall toward the drain, the condition of the existing tiles and grout, and whether the wall junctions show staining from earlier leaks.

Some things can only be judged on site. The technician looks at the substrate, moisture readings, the age and state of any old membrane, and the shower tray and pipe penetrations. Crack width, whether cracks are active, and how far water has tracked behind the wall finish are also assessed in person, as is the choice between a liquid membrane, a sheet system or a coating for the particular surface. Published rates give a starting range only: bathroom waterproofing is listed at SAR 15–40 per m², epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², and bitumen membrane at SAR 15–35 per m². The final figure depends on what the visit finds, so no firm total is given here.

To help the technician, have the bathroom area in square metres ready, note any crack lines and their length, and say which rooms sit above other living spaces, since that affects the choice of system. Tell the team when leaks first appeared and whether they worsen after use. Clear access to the drain, the shower tray and the wall behind the taps saves time. If a crack needs sealing, crack injection is priced separately at SAR 40–120 per metre, so measuring its length in advance makes the quote easier to read.
