Most towel warmers aren't designed to provide supplemental heat. Some of the less expensive brands are really only good for taking the chill off of bath towels. Runtal makes towel warmer/radiators that get warm enough to function as sources of supplemental room heat. Unfortunately, they also cost a good bit more than some other brands. If you shop around though, you should be able to find the smallest "Radia" model for around $500. Given that your bathroom is so small, it might be a good solution for you. It's rated at 1536 btu. The smaller "Omnipanel" models might work too, but they're usually slightly more expensive. I have an Omnipanel model as the only source of heat in my laundry room. It keeps the room comfortable in the coldest weather, and it's great for drying laundry that I don't want to put in the tumble dryer. The electric under-floor warmers are similarly not designed to provide supplemental heat. They're designed to simply take the chill off of the floor. You might feel warmer is you're not standing on a cold floor, but the rest of the room won't benefit from any extra heat. Here is a link that might be useful: Runtal Radia Towel Warmer/Radiator

Plumbing AND electrical will be your biggest expense. If you open the walls, you have think about an electrician, too. You may not be able to put a tub and shower into the existing plumbing for your two sinks. The trap for the sinks is under the sink, not in the slab, and you will need them in the slab for the shower/tub Raising everything might be possible, but will look cheap. Plus, stepping into a tub that is raised will be inconvenient, and possibly dangerous. I don't see how you will avoid cracking the slab if you move the plumbing. I would not be surprised if your water lines were in the slab too.

The high sq ft cost of the concrete must have been for a slab poured around 6-8" thick, correct? I would see that as being your least expensive solution when you take into consideration termites and the cost of other materials. I'd say try a brick patio, but you'd still have the expense of building it up to your preferred height. A concrete slab is the way to go, all factors considered.

There are absolutely no pluses about building with stellar. 2 years later after moving into our house we regret ever falling for the sales spiel. We already spent over $500 000 on that house that was built to poor standard that the real estate agent we asked to value our house said that we would be better off pulling it down and starting again rather than selling and moving. We should have raised voice when we observed that they didnâÂÂt use gravel to elevate the foundation before they dug the trenches. Again we had to spent a lot of money on replacing the vinyl windows because they start to rotten after a season. We were really disappointed by realizing how low quality products were used by them. We had to spend another $1000 dollars for the widow replacement since we hired window choice (Mississauga) for all the works. Polaris might be a good option for you so consider them. While selecting a window replacement Company, be so sure about their reputation so that you will not have to regret afterwards.
