Bleach then seal it with grout sealer... Who in the heck decided tall men should stand and pee into a short toilet, anyway?

This has been discussed on the Cleaning Forum. Many found good results by removing the tank and cleaning between the tank and the bowl unit. It seems that liquid can get trapped there and create a stench when dried. It may not be coming from your grout.

I was going to say the same thing Dilly did. Please try doing what she suggested--I had the same problem, it drove me crazy. When we finally cleaned between the tank and bowl presto, problem solved. My husband also used some clear silicone and sealed the area where the tank and bowl met. No more odor and it's been years now.

You are correct, sealers help with staining but grout is supposed to breathe. Vapor transmission is part of how the tiling system works. I would think clorox would seep through the grout to kill the bacteria. Maybe try some Nature's Miracle too.

Before taking the toilet apart, try spraying a cleaning solution into the crack between the tank and bowl. Clorox Cleanup, say. Slip a flat paper towel in there and move it around to absorb the dissolved urine that's gotten back there. Just keep floating a clean paper towel between the two units to pull the fluid out. You'll see when the towel comes out clean. Do that under the base of the toilet too if there's an open space (not caulked). Stuff can seep under there too. Cover all bases, lol. It really helps when there's a lingering odor.

I will never understand, lol.

Hmmm, ok, I'll try these things. I used the steamer on that section, but maybe I'll try slipping a paper towel in there.

I talked to a woman at the pet store who said there was a pet odor product they sold and it got raves, so I might try that, too. I don't have this problem in our en suite...we have an elongated bowl that is ADA height in there. Maybe that is why, huh? ;>

Maybe that's Nature's Miracle she was referring to. It's supposed to be 'the best' product out there for pet odors.

Above, I meant to clarify that, yes, the sealers don't waterproof the grout. (It needs to breathe. They're used for stain resistance.)

I would highly recommend getting a small hand-held black light, available at most pet stores. A few waves of the black light over the surfaces in your darkened bathroom should show you exactly where the problem is - if it is indeed an aim issue. You can then use Nature's Miracle or one of the other enzyme cleaning products on the lit-up areas.

I do this in my young son's bathroom to make sure I'm getting everything clean. Small boys have terrible aim. And, sadly, I've sometimes found that the grown men who use our powder room during parties don't do much better.
