## Questions & Answers

**Q: I need to order a replacement tank cover.  Which model is the tank cover?**
A: According to the Kohler website, the Kohler K-3978-0 Wellworth Elongated 1.6 gpf Toilet is made up of the toilet bowl (K-4198) and the water tank (K-4468). I don't know the model number for just the tank cover.

**Q: Is this a chair height toilet?**
A: The rim on this model is 14.5" above the floor.  Seat height will be slightly higher, depending on the model of seat used.  Standard rim height for US toilets is 15", so this is slightly lower than most, and definitely lower than ADA toilets.

**Q: what lid should I get for this toilet, the one suggested is "ice Gray' Is that white?**
A: In my opinion Ice Grey would be light grey. The toilet is white. You can choose whichever color you want to match your decor. We chose white.

**Q: does this come with toilet seat**
A: I found out that it does not when I received the shipment.  It actually comes in 2 separate boxes.  Its not like a whole assembly like you would get from HD or Lowes.  You can get the standard  Kohler seat from HD or Lowes for less than $20 (the same one you would get in the whole toilet package).  Don't forget the wax ring as well.  It is hard to find this toilet with the 15" height from local stores which is why I ended up ordering it online.
