The building in which I work was built about 15-20 years ago. When they installed the drains in the cement floor they left them up about a 1/4". It looks like they intended to put ceramic tile over the floor but didn't. The floor is a fridge floor that has dollies going in and out from time to time and raised tile would only hinder this (maby that is why that didn't instsall the tile).
My question - Is there any way to lower these drains to the level of the cement without replacing the floor?

The 1/4 inch is normal because its set up to get the toilet bolts in the flange to bolt toilet. Is this flange every going to be used again" To lower the flange you will have to cut concrete and lower part of the line. If you cut the flare off of the flange nicely it can still be used as a toilet later. The make metal repair rings that you can Tap Con into the concrete floor to hold the toilet over the 3" drainage. Or just cut flare on flange and stuff some paper in hole and pour a Little concrete in it to cap it for good

Lower them to the level of the floor. If you ever decide to usilize them they can be easily accessed and used.

Dude01...

I think 21 boat misread this one... ;)

You may be able to simply rotate the floor drain to lower the strainer... OR you may need to break out a little concrete from around the floor drain AND THEN lower the strainer by turning it CLOCKWISE. Then you would simply patch the concrete.

Otherwise, could tile the floor and use a BEVELED transition molding just at the entrance to the fridge (sold at all home improvement stores). That should make it easier for carts to enter.

Let us know if need more here...
