2 x 12 Joists spaced 16" on center are good for any normal bathroom. Make sure you figure out wherte your drains will be so it is not on top of a joist.
In a typical home, the surface flooring (such as wood, carpet or vinyl) rests on a subfloor, which rests on joists -- a series of closely spaced parallel beams that support the floor or ceiling loads. Joists are usually supported by a sill (a long horizontal timber that's the lowest part of the framework and rests on the foundation) or a girder (a large beam that's the main support of the building). When replacing rotted floor joists it's important to be sure the girder and sill are still intact.Typical costs:If only a few joists are rotted primarily at the bottom, they can be repaired using a process known as "sistering" -- after the rot is cleaned away and the timber treated to prevent more problems, a new joist is laid beside the old one and fastened to it. Total costs will depend on the extent of the damage and the ease of access to the joists (through a basement or crawlspace), but in general sistering averages $100 -$300 or more per joist, and could run $1,000 -$3,000or more to repair a tilted, wavy or bouncy floor under an average room.If the floor joists are extensively damaged, it will be necessary to support the house with jacks while the joists are removed and replaced. In many cases, the sill may also be rotted and need replacing. Costs can run $10,000 -$30,000 or more for a typical home, depending on its size, the extent of the extent of the damage and the ease of access to install jacks and replace the timbers. If the damage is limited to just one section of floor joists, the project could run $5,000-$10,000.What should be included:Joists carry the weight of walls, furniture, people, appliances and anything else placed on the flooring they support. Usually wooden floor joists are 2"x8", 2"x10" or 2"x12" timbers -- their size depends on their length, the amount of "load" they're designed to carry and the building codes in effect when the house was constructed. The Family Handyman explains how joists work.If there is sufficient access through a basement or crawlspace, floor joists can be repaired or replaced without significant impact on the rest of the house. However, if there is limited access, all furniture and appliances must be removed from the affected area and the flooring and subfloor torn out. The Family Handyman explains how to "sister" damaged joists and HammerZone.com describes using a jack to raise a slightly sagging floor.Additional costs:Floor joists can be damaged by boring insects such as termites or extended exposure to water. Before you replace damaged floor joists, you must exterminate the insects or improve the drainage and ventilation so the problem won't reoccur. Costs will vary widely depending on the extent and nature of the original problem.Typically floor joists are repaired or replaced working from below, in a basement or crawl space. But if there's limited access to the joists, it may be necessary to work from above, removing the flooring and subflooring to repair or replace any damaged floor joists. Costs will depend on the extent of the damage and the type of replacement subflooring and flooring chosen.
Bridging is always a good idea. I did a little construction work a long time ago, and we always used thin metal strips between the joists in new construction instead of wooden bridge work. Here's a picture of metal bridging between joists. In this picture they have bridging every third of the way, or every 4' on a 12' floor. http://www.rd.com/familyhandyman/content/34459?trkid=tfhplus_november_07
Obtain a stud finder that uses sonar to locate these. Available at most major hardware stores - they work great for hanging heavy objects on a wall in the home, too.
If by any chance you have an earth floor in either the garage or, more likely, the basement, this will not work.
Museum of Bath at Work was created in 1978.
I'd pull the tub and cut out the rotten floor first. That will give you more light to work in the crawlspace after you remove the subfloor. You'll want to check the joists for damage too. Phil
Yes. If it were not soluble it would not work well as bath salt.
No
It depends on floor level too; assuming you are on the ground floor, the pipe work and tubing acts like a cage that helps to hold materials together, meaning, less flying debrix. Additionally most bath tubs are extremely heavy.
No you do not have to bath after using salt because your skin wont work.
Scientists who work on the ocean floor are called marine biologist
yes
