What a wet room asks of the floor
A wet room asks the floor to do three jobs at once: shed water toward a drain, stay safe underfoot while it does so, and hand over cleanly to the dry floor beyond. Where a wet room disappoints, geometry is usually the first place to look: the fall was too shallow, the drain sat in the wrong place, or the threshold was treated as an afterthought once the tiling was already underway. Settle those three things and the choice of stone becomes a comparatively easy decision made from a shortlist rather than a rescue operation.
Falls, drains and the layout that follows
Decide the drainage strategy before the tile, because it dictates unit size and coursing. A central point drain pulls falls from four directions and suits smaller modules. A linear drain against one wall lets the whole floor run in a single direction, which allows larger units and fewer cuts.
- Set the drain position on the plan before choosing a module size.
- Use smaller units where the floor has to follow falls in more than one direction.
- Keep the fall consistent so water does not stall in a flat patch mid-floor.
- Check that the door swing does not sweep across the wettest part of the floor.
- Confirm the waterproofing layer and its detailing before any stone is set.
The threshold: the detail worth getting right
The transition between wet and dry is where water escapes, where movement concentrates and where two different bed build-ups have to meet. A single cut stone threshold piece, bedded solid and slightly proud of the wet-side finish, works better than a joint between two fields of tile. Keep the waterproofing continuous under it and turned up at the edges, and resist the temptation to make the piece decorative. On accessibility grounds a flush threshold may be preferred, in which case the fall and drain capacity have to do the work the upstand would otherwise have done. Whichever version is chosen, settle it on the drawing rather than on site.
- One solid piece rather than a joint between two fields of tile.
- Waterproofing carried continuously beneath and turned up at both edges.
- A plain profile, since a shaped threshold traps water and grit.
- A confirmed decision on flush or upstand before the bed depths are set.
Tile size in a small wet room
Large modules look generous in a photograph and then fight the falls in a compact bathroom. Specifying wet-area tile in gauged depths keeps bed thickness predictable when several planes meet, which is exactly the situation a shower floor creates.
- Smaller units on the shower floor, larger units across the dry field if you want contrast.
- Consistent depth across both, so the two areas can be laid to one bed thickness.
- A joint width that a brush can actually reach and clean.
- Full units against the most visible wall, with cuts pushed to the concealed side.
Finish underfoot and finish on the wall
Floor and wall want different faces. Underfoot the priority is grip when wet, which points toward a brushed or bush-hammered face in the shower area. On the wall the priority is light and cleaning, where a smoother face is easier to keep and reflects what daylight there is into what are often compact rooms. Where the room is small and light is scarce, our lighter limestone tile line keeps the space from closing in without pushing you toward a slippery floor.
Sealing, grout and movement
Wet rooms concentrate every maintenance issue a stone floor has into a few square feet, so the small choices carry far more weight here than they do across an open living floor.
- Choose a grout suited to constant wetting rather than a general-purpose product.
- Leave movement joints at internal corners and at the room perimeter.
- Seal after the floor is fully dry, not on the day the tiling finishes.
- Avoid acidic bathroom cleaners entirely on limestone, since they etch on contact.
Permits, imports and lead time
Building work on Bonaire has followed new rules since 1 July 2017 under the Wet VROM BES, with the BES Bouwbesluit setting general standards for structural safety, user safety, fire safety and accessibility. A bouwvergunning is issued by the bestuurscollege, which must decide within sixteen weeks of receiving an application, extendable once by up to eight weeks. On the import side, the tax rate is set at nil for all goods and ABB applies at 8 percent on the import of goods, calculated on the customs value of the goods plus insurance plus transport. Plan the stone order against both timelines rather than one, since a permit decision and an ocean freight window rarely land in the same week without being deliberately coordinated.
Specifying a wet room with us
Send the bathroom plan with the drain position, the door swing and the waterproofing build-up marked, and we will propose unit sizes and faces zone by zone rather than a single tile across the room. We will confirm calibration so the shower floor and the dry field share one bed depth, and we will hold a matched lot if the project is phased. Samples go out first so the wet grip can be tested by the people who will actually use the room, barefoot and under running water rather than dry in the hand. Quotes are written in US dollars, and the freight leg into Kralendijk can be planned against a published weekly sailing out of Florida, which keeps the delivery date honest against the permit timeline. Get the fall, the drain and the threshold right and the stone will do the rest of the work quietly.
