Contractors must provide the lien waivers if you request them. You should always ask for a lien waiver from the contractor when you make a payment. This will prevent a subcontractor or material supplier from putting a lien on your home if the contractor does not pay the bills. The following case history explains why lien waivers are so important to consumers:

We all want a bathroom that would be a reflection of our personal style and be able to deliver the comfort we need at the same time. However, aside from that, it’s also important that it has the right fixtures and amenities that are capable of providing function and value as well. Fortunately, through careful planning and choosing the right design, you can have it all.  Here are some of the best tips that could turn your bathroom remodeling dream into reality.
Due to the proximity of the bedroom to one’s bathroom, noise is usually an issue for most homeowners. If there aren’t any windows attached to the bathroom, an exhaust fan should be installed as it can help in removing moisture. Likewise, if you want to reduce the noise made by your toilet tank while it’s being refilled, then you should install a modern inlet valve.
You’re right that there should definitely be some kind of ventilation in a bathroom to prevent moisture build-up. My husband and I are remodeling our bathroom and removing the window that is attached to one wall (it’s just so awkward having one there) and installing a vent to replace it is definitely something we’ll want to look into. I’m not sure if we already have an inlet valve, but our toilet can be rather noisy, so we’ll have to talk to the contractor about that, as well.
Take the time to chat with friends, family, and neighbors about the renovation work they have done, and the challenges they have faced during the process. Having a wealth of information from homeowners who have been in your shoes can be invaluable in the planning process, and this information may alter your end plan.

Having  a floor heating system that can be laid under the tile in the shower is a nice add-on, not only is it more comfortable ambiant air temperature, but the feel of warmth on normally cold tile in the morning is a nice change that you will certainly enjoy.  It’s important to ensure that the heating system you’re going to get can be used inside the shower. For those who are interested in this type of bathroom, it is ideal to consult a professional who would help you plan the layout.
Living through a home renovation can by a trying experience—one that’s often filled with dust, exhaustion, and plenty of take-out. Even the most meticulous of contractors can’t keep dust and dirt from flying everywhere, so know that your house will not be as clean as you would typically keep it, and try not to let that bother you. If you think it will be too much for you to handle, it’s not out of the ordinary to rent a place to stay, go on vacation, or live with friends or family for a few critical weeks until the home is a bit more "liveable." 
Learning which items to spend your money on goes hand-in-hand with making a realistic budget and determining a sensible scope of work. The earlier you can make this determination, the more likely you will stay on track with costs. Think about which items you will use most frequently, as these are products that might be worth the higher price-tag. If you're on a tight budget, you might want to save on cosmetic finishings, as these items can be easily changed with time.
You should never attempt bathroom remodeling work yourself unless you are 100% positive that you can do it properly. This means that you should never try bathroom remodeling work that you have never done yourself or have no training in because any mistake you make during a bathroom remodel could potentially send the total price of the project soaring. Most people hire contractors to handle the following:

Improving your home is a solid investment at any level — but if you have up to three thousand dollars to spend, a great place to start is by upgrading either the kitchen or bath. Either room is a good choice and you don't have to do a complete floor-to-ceiling remodel to reap financial benefits. In fact, modest kitchen or bath updates can be your best bet for a big return, netting, on average, an 80-85 percent return.
Thanks for these remodeling tips. I didn’t know that it’s important to make sure that your new bathroom is ventilated properly especially if it can help prevent mildew buildup. I’m kind of interested to learn more about how to take this consideration into the initial planning of the project, and how to determine where the best location of the vent should be.
"A remodeling project is going to affect every room in the house," says A. J. Paron-Wildes, general manager of DreamMaker Bath & Kitchen in St. Louis Park, Minnesota. "The homeowners need to take down pictures, move vases, and pack away valuables before work begins." While you're at it, take steps to protect your immovable fixtures, including built-in cabinets and chandeliers. Have flooring covered with cardboard sheets if it needs to stay in good condition.
