All bidets I've looked at including Tushy seem really complicated to install (basically having to redo the plumbing) and I don't understand how so many people can just buy and install one like it's nothing. Am I imagining things?

Edit: Not in the US and the plumbing looks a bit like this, but without the nuts so you can't easily disconnect a part of it: https://static.byggahus.se/attachments/images/large/341/3416...

If you can handle putting the nozzle on your garden hose, you should be able to handle it.

In the US, the water pipe almost always connects to the toilet through a small shutoff valve. After the valve, it connects to the toilet through a "supply." The supply is basically a short garden hose, with screw-on connections at both ends.

Shut off the water at the wall. Flush to empty the toilet tank. Unscrew the hose at the toilet, and screw that end into what amounts to a y, or splitter that comes with the bidet. From the splitter, screw one side back into the toilet connection; the other goes to the bidet itself. Turn back on the water at the wall.

(This is for a simple cold-water bidet. If you need heated water or electricity, it can be more complex.)

I mean, but don't you need warm water and/or electricity? I can't see liking a bidet if it's basically just cold tap water shooting up my bum. Not sure that's going to do it for me.

I've always thought that both hot water and electricity would be a minimal barrier to entry for a bidet. And that neither of these exist in a typical toilet closet. Am I fundamentally wrong about this??

Whether you need it probably depends on your climate and your house.

Water in pipes inside a house's "thermal envelope" is presumably around 72 deg. F. I wash my hands with "cold water" without wincing. Tap water strikes me as tepid if I drink it without ice.

If your pipes run through an outside wall in Canada, it might be a different story.

If you do need warmer water, and the bidet heats it, you probably just need an electrician to fish a wire and add a receptacle. That's not outrageously complex, usually, but I tend toward calling a professional for anything behind the walls.

> Water in pipes inside a house's "thermal envelope" is presumably around 72 deg. F.

The pipes in my house are in the crawlspace underneath the house, which is definitely nothing like 72F this time of year. Any hot water more than 10 feet or so away from the water heater runs pretty cold for several gallons.

That sounds like a good weekend project, putting split foam insulation around your pipes. 8' runs are a couple of bucks at the big box stores.

It's not quite as efficient, but I put in a recirculation pump and a timer to keep the water warm throughout the pipe during the day. The clothes washer was never getting warm water, and we wasted a lot at the shower waiting for warm water to reach it.

it's really not that cold. i can't do cold showers at all and tap water bidet feels nothing like it.

Same, I don't even like washing my hands with cold tap water, but cold bidet water is no issue.

The bidet heats up the water instantly, there is no requirement for a hot water supply. Just connect it to the existing water supply the toilet uses.

You do however need electricity. I had to run an extension cord for mine, which I tucked away in low profile conduit to keep things tidy looking.

It depends on what your toilet supply lines are like and if you use a cold water only or a cold/hot water bidet, but a cold water only one (not nearly as uncomfortable as imagined before trying it) is very easy to install as long as your supply line has a shutoff valve and is relatively flexible.

It takes 15-20 minutes and it basically consists of unscrewing a few things and screwing them back together again.

I bought a Tushy during the pandemic, it took about 10 minutes and a flathead screwdriver.

I liked it so much that when I had a new bathroom installed a year later I put in a Toto Washlet.

I feel like Toto is failing with their marketing, since people are not really aware of their products outside of Japan. No good and cheap alternatives either

Toto is failing with their prices. I know they can print money in Japan, but it looks like they don't really want to be competitive elsewhere. Sooner or later someone will persuade the right influencer to start a bidet craze and they will get 10x bigger than Toto overnight.

Yep, this is what I've been thinking!

Is Toto really that better than others? I have both (very old Toto vs Chinese no-name) and I see no difference.

You can pry my toto drake 2 from my cold dead hands.

Duravit aren’t cheap, but are much cheaper than Toto (at least in the UK) whose pricing is kinda outrageous.

I’ve got a Duravit toilet here in the US, and I'm on the hunt for a compatible cold-water bidet seat under $300 on Amazon. I originally went for a Brondell, thinking it would match the shape and dimensions. But halfway through the install, I realized it wasn’t going to fit around the seat connectors. Duravit's own bidet seats are around $1,000-- I'm tempted, but they look like a lot of work to install. I’m starting to wonder if I should just upgrade the whole toilet to a model that comes with a bidet.

Those are compression fittings which we also use in the USA for sink and toilet connections. Standard size here is 3/8 inch which is the outer diameter of the tubing. They are easy to work with as you only need a tube cutter (or hacksaw with fine tooth pitch) and a wrench. You cut the tube, slide a compression nut over, slide the ferrule(s) on, insert the tube into the fitting, finger tighten the compression nut, make sure everything is aligned then tighten nut with wrench. No solder, no fancy crimp tools. You can disassemble and reassemble without leaks. The only issue is the ferrule winds up becoming swaged to the tube after wrench tightening so you have to cut the tube end off behind the ferrule if you want to replace the nut.

However, instead of using rigid metal or plastic tubing you commonly find a flexible hose assembly[1]. Only fancy installs use custom formed polished rigid tube for the look. We also tend to leave most of the plumbing in the walls and only the shut off valve protrudes from the wall. Maybe there are flexible hoses available in your region.

When I installed my bidet all I needed was a 3/8 compression tee[2] which they make specifically to tap shutoff valves. The bidet came with a 3/8 connection hose so that went to the tee and I was up and running. The big issue was electric - no outlets in the bathroom. So having seen how Japan loves extension cords I too used one, ran a 12 AWG cord out to the hall to a GFI adapter plugged into a socket. Jank but highly unlikely to cause a fire.

To follow on to user infecto’s sibling comment, for most U. S. homes, it is probably fifteen minutes of work. Shut off water, connect t-line, bolt down new toilet seat, sorted. It shouldn’t be complicated for most installations.

I ended up buying a travel bidet because I couldn’t install one at our house for various reasons. It’s basically just a squeeze bottle with an angled head. Works great!

Just don't get it mixed up with your water bottle!!

US based plumbing. You are imagining things. Most/all resi toilets in the US use a flex hose to connect the toilet to your water supply. Its usually a threaded connection. All these style of bidets simply have a T off of this connection.

Not in the US. The pipe just goes straight into the toilet. When googling around seeing articles about installing Tushy when you have rigid pipes they are still much more flexible than mine, with separate parts you can disconnect and replace.

I was in the situation you describe when I got a bidet. It's possible to replace that pipe -- a little more work of course, but it's still turn off water, replace pipe with flexi-hose, connect bidet.

I posted a picture in my original comment. Was it in the same ballpark? The difference with mine is that there are no nuts on the pipes next to the wall. It's one solid construction going from the sink through the toilet to the shower.
