Product Questions & Answers

Q: Could I use the 36 .in X 60 .in wedi fundo primo shower kit, along with this 48 .in X 24 .in wedi shower base extension, to create a 36 .in X 84 .in shower base?
Yes, you would just cut 12 .in off the 48 .in side. You still want to maintain the lip at the edge, checkout the video at the bottom of the product page. These extensions are sloped but cutting the longer side to fit still maintains the slope in the right direction.

Q: Could you add the 73783528, 24 .in x 48 .in base extension on the 075100015, 48 .in x 60 .in Fundo Riolito shower pan to make a 48 .in x 84 .in sloped shower pan?
Yes, (075100012) you had wrong # for the, 48 .in x 60 .in Fundo Riolito shower pan. This is a four way sloped pan and at the edge the slope starts from the corners so a sloped extension would fit perfectly.

Q: Can this base extension be used with curbless Fundo Ligno pan?
This extension is too thick to be used with Fundo Ligno bases. There is a Fundo Ligno specific base. The SKU is W_FL_EXT so simply search for that and you will find it.
