Is a bathroom in a Jazan clinic worth waterproofing properly, given how close the city sits to the coast? The short answer is yes, and the location makes the case stronger. The centre of Jazan sits about 7 m above sea level, and the city is about 1.9 km from the sea coast. Clinic bathrooms see constant water use and frequent cleaning, so a sound waterproof layer protects the floor beneath and the rooms below it. Bathroom waterproofing for clinics in Jazan is typically priced at SAR 15–40 per m², and the exact figure depends on the surface area and the condition of the existing floor.

Our inspection starts with a walk-through of the bathroom floor, walls and the joints where wall meets floor. The technician looks for cracks, hollow sounds under tiles, and signs of past moisture such as staining or flaking paint on the ceiling below. Where a crack is found, crack injection is priced at SAR 40–120 per metre, and it is usually recommended before any coating goes on so the repair is sealed from the inside. The inspection then records the measured floor area so the quotation reflects the real surface to be treated and the method suited to it, whether a coating, a membrane or spray foam at SAR 20–45 per m².

Before the visit, it helps to clear the bathroom floor and walls of loose items, and to note any leaks, damp patches or areas where water pools after cleaning. Tell us which rooms sit directly above occupied spaces, since that affects how the work is scheduled. Keep records of any earlier repairs and bring them along, as previous coatings can change the preparation needed. If the clinic also has a basement or a water tank, mention those now, because basement waterproofing is priced separately at SAR 50–150 per m² and tank coating at SAR 25–60 per m².

For clinics, work is scheduled around patient hours and kept to the areas that need it.
