I had the same problem last year. I had a small leak in a horizontal steel
drainpipe on the bathroom sink. The pipe was rotten. Luckily, I had a
vanity to covery up my work, because I had to cut a hole around the pipe.
The pipe extended into the wall about two inches and was screwed into a
larger vertical pipe.

It sounds like you don't have the vanity, so cosmetics will be more
important. You might try disconnecting the trap and then putting a pipe
wrench on the horizontal pipe to see if you can twist it out without
disrupting the tiles. If so, you might be able to replace it the same way.
However, there's probably a good chance that you'll have to carefully
removing the surrounding tiles, and then saw a whole in the wall if things
don't go well.

Bath Sink Drain (50 yrs old)

Hi,

I belong to a little 50 year-old brick bungalow in the midwest.

There's a small bathroom that's never been remodeled. A small
sink with a U-trap, drain running horizontally thru
tiles into the wall maybe 14" above the floor.
