water proof with a PVC liner available at a tile supply store- the same as used in tile showers. You will need to build a pre-slope mortar bed with a diamond or expanded metal lathe. Install the PVC liner over it with the pre-fab corners-- then put another mortar coat on top of that.. THat is the traditional way.. BUT, one way people are doing it now (I did this) is to build your form, then do the pre-slope with a regular mortar (Or portland cement with a polymer additive and fine sand)-- then install a fiberglass sheathing over the top of it-- much easier than the PVC liner. I would like to talk to you about your concrete tub. I build concrete counters and do decorative concrete overlays and have always thought about doing a tub, but hadn't decided the best way to build it.. Are you doing it with a gunnite and rebar? Curved? Straight edges? Email me |
