Product Description

Wedi's Fundo Primo is a fully waterproof, pre-sloped shower floor base with an integrated waterproofed point drain connection for fast-track installations. It eliminates the many different steps and products involved in traditional mortar bed or semi pre-fabricated sheet or liquid membrane system installations. Fundo Primo can be customized in the field and cut to size, allowing it to be used on shower stalls smaller (or larger, with extensions) than the nominal size of the product. Fundo Primo is available in select sizes featuring centered and off-centered drain options.

The bases come with even perimeter thickness for easy recessing into subfloor construction, however curbs may also be used with Fundo Primo. Fundo Primo can be directly tiled over upon installation and there is no limitation to the size of tile or type of tile and cement based tile setting materials selected.

Fundo Primo is available with select drain cover options. Due to the precise slope fields of the Fundo Primo, large or small format tile may be used. Within each slope field the tile will be fully supported over an even yet sloped surface. Where slope fields meet, grout lines should be designed when using tile larger than 4“ x 4” as these should not span across two slope fields.

Product Questions & Answers

Q: Iā€™m planning a 36ā€ x 42ā€ shower. Can the 36 x 48 base be shortened 3ā€ on each end?
Yes, you will want to cut on both sides to maintain center drain. Make sure you reapply the lip on the cuts. The wedi video at the bottom of the product page will show you how to do it.

Q: In the picture I see a diamond shaped basin however, all the diagram pictures are square or rectangle. Is there a specific diamond basin?
There are no currently available diamond-shaped bases. The image was provided by wedi and is a few years old.

Q: How durable are these pans. I noticed you can dent them just by kneeling on them. Will they dent after tile is installed over pan?
Once you thinset and tile these are extremely durable and one of the best waterproofing products on the market.
