After hours of searching for a shower pan to mount our CW-200 cassette toilet, I found Sierra Engineering. Model 70 features a 40" x 25" pan with a raised area for the toilet. The cassette toilet fits perfectly in the toilet mount area. Eric at Sierra Engineering worked with me to make sure I found the perfect size. Sierra Engineering offered the best customer service I have experienced in a long time. Eric even called me immediately before the mold was poured to make sure everything was correct. Delivery was quick and the quality far surpassed the other cheap flimsy pans I had previously tried and returned.
