I finally followed my dreams and got a Toto Washlet S300e for my home! NIB off eBay for a few hundred off MSRP. After getting the electrical rewiring done to accommodate the plug and hooking it all up, I realized my blunder - I completely missed that this was a 'Round' model and not 'Elongated' (the other Washlet model I was comparing to only came in Elongated, and I overlooked this critical detail on the s300e). There were no returns on this item, which is relatively sensible in a 'no returning used toilet seats' policy. Is there a way to order parts for just the ring seat and cover in 'elongated' that will fit with the bidet base?
The seat is heated, which makes the swap a bit more complicated as well. I see Toto sells replacement *lids*, and they sell standard replacement seats that affix direct to a toilet, but I haven't been able to find the bidet seat itself without just getting a whole new Washlet unit. I need to know A) where I can get an elongated seat as well, and B) if there's a mechanical reason I couldn't put that longer seat on the base.
