Question 1

How to I install the seat?

Accepted Answer

No instructions—written or visual. I have installed MANY toilet seats in my 68 years, but this is not like any other. Directions for dummies 101: in the plastic bag are two grey bolts and two black wing nuts. The toilet seat cover has the hinges attached. I popped the hinge caps off with a screw driver. Set aside. After removing the old set, put the two grey bolts through the holes in the toilet from the top. Underneath place the black wing nut on the bolt. I could not just screw the wing nut onto the bolt as the nut has a protruding piece which hit my toilet. So I held the wing nut in place keeping the protruding piece flush with the toilet and screwed the bolt with the screwdriver from the top of the bolt so it was snug—not too tight as with any plastic tightening too much will cause the plastic to break. With the hinge caps still off, set the cover over the top of the bolts. It should fit nicely. Place the hinge caps over and rotate to the locked position. It took no force to accomplish this part. Really simple and easy once you figure it out. Instructions would have been helpful.

Question 2

How large is the  "hole"??  I presumed they are all standard, but the one I have now is smaller that before..

Accepted Answer

Seat is 14 1/4 by 15 1/2.  Hole is 8 1/4 by 10 1/4.  Overall length fr the hinge holes to the front is 17".  Hope I didn't give you more than you ask for.

Question 3

Will this fit a 16.6" X 14" round toilet?

Accepted Answer

It fits the 14" wide but may be shy on the 16.6" , unless your measurement is from the screw holes to the front of the toilet. Then it would be fine.  My toilet is standard round, like most are unless you have a more commercial style one to fit it on.

Question 4

What are the dimensions of the seat?

Accepted Answer

15" length (from front to back not including the tabs) and 14" width.
