Hi Sleepless :-) Cement=IPS Weld-On 795 medium body clear cement for flex and rigid PVC Black vs white is asthetic and stocking issue. Nearly everything related to ponds are black plastic so the suppliers stock black hose. Nearly all other plumbing suppliers stock white (cream) Gray and black are usually special order 50' rolls. Installation note: Stay away from female threaded schedule 40 fittings. Use schedule 80 in these applications. There is to high a risk of the internal pressure of the threaded connection causing the part to split. White teflon paste for threaded PVC fitting, NOT teflon tape, same rule as above. Silicon grease is a good friends when connecting unions. Grease the threads and "O" rings for easier removal and sealing the "O" rings. Vinyl tubing and barbs are a one-way trip. Once on they have to be cut off (after a period of time in place)unless a heat gun is used. Unions can come apart as often as needed. Cement doesn't break down, good for as long as the PVC is. Check online for some of the hard to find fittings, flexpvc.com was listed above, they do have a number of the hard to find parts but there are also lots of other suppliers out there. Menards, Hm Depot and Lowes are VERY limited for the stuff we need when it comes to plumbing. I get mine wholesale from the supplier as I've also done waterfalls, fountains and water features for commercial applications. Helps feed my hobbies :-)

I don't know about middle east, but yes, those are common in europe. Because washing with water is cleaner than wiping with paper after a #2. If there is a showerhead next to the toilet, as in the picture, it's called a douche. If there is a separate toilet bowl looking thing, it's a bidet. You probably seen those before. I think they are just too messy, so I like the japanese way where there is a automatic water wash system build into the toilet. I have been using them for years now and love it. Toto has one called Washlet. Kohler has the Numi and Duravit has the sensowash. They are more common now and a lot more brands carry them, even costco has them.(not by toto or duravit).. If you want one, Toto is probably the best..

"So it's become a choice between paying someone or not having it done at all." I'm limited physically too (and often mentally - lol!). you might have to find someone and pay them to do some things for you. Ask around with your friends for a young guy (HS or college maybe? at a church?) who needs to make some money. Make a list of priority things that need done and try to squeeze out 30-50.00 for a few hours of work. I hired a few guys to do a some things and got ripped off. That put me off for some time in getting more done. I finally connected with a young man (29) who has done work for my sister over the past 15 yrs. She knows his parents (I've been to their house). Even as a teenager he was huge and strong - and she wanted him to do mostly outside work. A lot of rock moving - her land is very rocky. He still does that for her some Sundays. He comes here on Saturdays for 3-5 hrs. He's done a ton of work around here - putting up shelves (taking some down), fixing cabinets, doors, locks, putting down some flooring, moving things around, caulking windows and doors. He also does 'low and high' things for me like caulking around bottom shelves of cabs, cleaning off high shelves and putting things up there. It keeps me from falling off of a step stool or being stuck on the floor until someone eventually finds me there... He's put up curtain rods, replaced my water pump, laid out and connected hoses for future plantings (that he'll do), cleaned up weeds and 'construction' type litter around here. He's even worked on my car. I'm finding it not as easy recently to lift the hood of my car to check water, put in pwr steering fluid etc. He's done some plumbing and some electrical work too. He's quick to tell me if it's something he can't do rather than say he can and mess it up. He's great on figuring things out (more creative and logical than my old brain these days) and problem solving around here. He's been working most Saturdays since last fall and there's enough work here for him for another year I'm sure. He isn't a speed demon but he is dependable, methodical, careful etc - which is much better. He works a full time job during the week but is saving up to buy some land up north of here by the end of the year. He's happy to have the odd jobs - close to his home, a friendly boss (me) who gives him things (ice cream maker, dishes, scrap metal, old appliances, a vacuum (too heavy for me to even move but they are young and strong and have a 2 story house)). He isn't obligated to be here every single Sat or at a certain time. I always tell him that his family comes first so when a family doings is on Sat he shouldn't be here, he should be with them. Financially I need to limit it to maybe 2 Saturdays a month now. In the summer my electric bill skyrockets and that will take priority for several months. I also need to save up for more flooring. Maybe you can find someone like this that you can trust who would like a few flexible hours to work around another job, school activities or studies.

You would also be asking a contractor to drill a hole in your new tub where one is not intended to be. I bet a lot of contractors would refuse to do that. Putting a hole there in a fiberglass tub may ruin the integrity of the tub structure. Drilling through a porcelain and cast iron or even porcelain and steel one is way beyond the capabilities of most. I can understand why you would want this, but you might have to give up on the idea. We have retractable hoses under kitchen sinks, because there is access to them if they might start to leak. This would not be so under a tub like yours. Having used a bidet hose, I know that the water from the sprayer likes to flow down the metal hose and drip onto the floor from the bottom of the loop where the hose hangs down. Again, this would be a point for rot under a tub, where one could not clean it up.
