Our powder room finished floor consists of the plywood sub floor on top of the concrete slab, with almost an inch thick, solid wood plank floor. We are not getting a good seal of the toilet on the wax ring. Seems to us that the flange needs to be higher? How do we do this? And is the flange supposed to be level with the finished floor, and then the wax ring is on top of that? Our home and this bathroom is over 40 years old. Does this cause us problems in trying to adjust the height of the flange (if it can be adjusted)

Also, our upstairs tub and toilet are above this powder room. Last night after a fairly long shower (15 min or so), we found this powder room toilet had water leaking out from the base at the floor (a lot of water). We had not yet put any caulking/sealer around the base of the toilet yet.

Why would the shower draining cause this? HELP!

Thank you!

How to Install a Toilet Drain Extension | eHow

Your bathroom drains are connected at some point and the water escapes where the toilet is not seated properly. Before you reseat the toilet properly, you may want to make sure there are no blockages in the drain line.

Purchase flange extenders and bring them level with the finished floor, Good luckm Tom

How do we do this?

Tom and Talaniman covered that well...proceed as suggested.

And is the flange supposed to be level with the finished floor

The flange can be level with the floor or it can sit directly on the floor...both are fine.

and then the wax ring is on top of that

Yes, that is correct. A wax ring with a neoprene center is the best if you can find it.

Why would the shower draining cause this?

The shower drain would cause this only as a result of the toilet drain being partially plugged up. If there is not an accessible cleanout under the toilet you may need to pull the toilet and snake the drain from there. However, I would check to be sure that your MAIN DRAIN line is not the problem by removing the main cleanout and draining a full washing machine load of water. if water backs up at the main drain cleanout then you need to snake the drain from that point...;)
