water leak at the base of the toilet.

The toilet sits on a flange, held down with two bolts. There is a seal (foam or wax) that goes between the flange and the bottom of the toilet.

You could have loose bolts, a bad seal, or a broken flange from over-tightening the bolts. Whatever, you need to shut off the water supply to the toilet, undo the bolts, lift off the toilet, and find out what is wrong, then fix it.

This happens to me on occasion. There is a valve attached to the flush mechanism that leaks and drips down on the floor. I thought it was a leak between the toilet and the floor, but it wasn't. If you have a foot flush unit, there is a plastic cap that goes over the top of the valve. remove the cover and examine the plumbing with a flashlight. If its the valve, you should be able to see it dripping or feel that it's wet.

I've replaced three of them over time in my unit. Camping world sells the replacement valve for about $20. I keep a spare with me now so when the next leak occurs, I don't have to make a special trip to pick one up.

It's fairly simple to replace. Two hose clamps and two screws.

What brand? I have been fighting a mystery leak as well on my porcelain SEALAND.
Replaced the vacuum breaker but that wasn't it..

Also check the hose clamps around the toilet. I had a leak this spring and a simply turn ofmthe clamp and no more leak.

Hose clamp and/or leaking valve would be my guess - actual leak between toilet and floor would be rare.

I called the tach at camping world. They are going to look at it in a two weeks. I was concerned about the water and the wood floors. He assured me that if there is damage, warranty will cover the repairs. I dont mind fixing stuff myself, but it is only a month and a half old. I shouldnt have to fix anything.

Had a riser installed on our new TT (May) and it started leaking between the top seal and the toilet. Tried tighten with a pair of pliars, no go. When I took it in three weeks ago, was told that the top seal was installed crooked. Seems if they had time to go back and repair, there was time to do it correctly initially, but................................ Waiting for a new end cap and a tongue jack (electric).
