    We are tiling the bathroom and after setting backer board, thinset and tile, we're raising the floor almost an inch.We won't be able to turn off the water because the knob will probably be right at floor level. We'd like to avoid having to solder an extension but... Are there any options. Thanks.

    You should explore the 1/4 turn valves. These do not have to be twisted around and around. A toilet supply valve should always be fully on or fully off, so there is absolutely no advantage to the older type valves. You might also want to consider opening the wall and raising the pipe several inches. Yes, it very well could mean having to sweat a joint or two, but unless you are totally inept, this is a relatively quick and simple job. I'd still recommend the 1/4 turn valve.

    How would a 1/4 turn valve help?

    If you cant or do not want to raise the pipe and its coming out of the wall you could buy a straight stop. This way the handle would be on top not on the end.

    If the pipe is coming out of the floor you could use an angle valve. This would put the handle on top also...away from the floor.

    How is your current valve attached to the pipe? Solder?

    You might find a round knob might have clearance where an oval one didn't. Then, while not as handy, they do sell the valves with a removeable key rather than a knob. You could probably get a couple of positions where the key could be engaged to avoid it hitting the floor. But, if this is either in the wall or coming out of the floor, the better choice would be to replace the valve. If it's coming out of the floor, BrassCraft sells a chrome plated 5" valve that slides over the copper stub, putting the valve up in the air. If it's coming out of the wall, they sell right-angle valves that would raise it away from the floor. Dahl makes a nice one, and probably others. It depends on how the existing one is attached what your options are. If it is threaded on, you may not have enough room to unthread it. If it is either soldered or a compression, you should be able to get the old one off and a new one installed fairly easily.

    A 1/4 turn valve usually has a lever rather than an oval handle, and it only turns 90 degrees so if it is above the floor, the handle does NOT have to rotate to hit the floor.
