It’ most usual for people to remain conformed to traditional orthodox approach when looking for a glass block bathroom window. They find out the desired size, look for a supplier and entrust it to them to find out the best suitable block sizes. Well, nothing wrong with that approach, because it enables you to have a well functioning symmetrical window. However, it deprives you from having something very exclusive. There are quite a few options open to you while undertaking the construction of a new window or even while looking for its replacement. You need not get restricted to just piling of the blocks. You could always use a mix of these two to get a very novel design.
Here are even steps to having unique and interesting window designs:

Step 1 – find out the size – It goes without saying that the most important step is to know the right size of your window. However, your choice is not restricted to the present size. While undertaking any renovation project for your bathroom involving window replacement, you need to know two things from your contractor. One is the size of the window that can be fixed in the presently available cavity and the other is how tedious it may become to change the frame of the window. Block windows are available in increasing steps of two inches in size. And, you can have very exceptional designs not only by having one block over the other. If it’s a new construction you can always ask the builder of the flexibility of sizes you can have. However, you need to talk over the subject before the builder undertakes the process of rough framing.
Step 2 –Decide your size of block sizes and combine those. By combining units of different sizes, you can make unique deigns. For instance, you could have a very dramatic design using a combination of 6″ x 6″ with 12″ x 12.
Step 3 – Choose a block pattern – You get block windows offering varying levels of privacy, from moderate to high. Naturally, you would like having maximum privacy in the windows of the bathroom. Check the Iceberg pattern for your shower unit. For a bathroom window away from the wet area, a wavy design may prove to be ideal.
Step 4 – Select clear, colored or frosted glass blocks – The best thing is that you need not necessarily have clear or colorless blocks. For adding an element of excitement to the window, consider having frosted or colored item in mixed up sizes to get outstanding results.
Step 5 –Assess which of the two, the framed or a frameless window would most suit the situation. While framing window in a new construction, the design of window in vinyl frames that has nailing fins enables the installation very much like a conventional vinyl window for a new construction. In case of a remodeling project when it’s not possible to change the size of opening, the best option would be go for a frameless window that can be had in incremental sizes of two inches.
Step 6 – Order your window –You will find it to be a very difficult project, if you decide to do it in a block by block manner, by laying each block individually. It is far better and more practical to go for prefabricated window assembly, which results to a lot of labor saving and delivers a better quality of finish ultimately.
Step 7 – Don’t restrict the use of multiple blocks of different sizes to the bathroom alone. Having fun with diverse sized blocks need not be limited to the bathroom window. Try mixing sizes in a partition wall or glass block shower or a basement and garage.
These seven points should sufficiently prepare you to try a nontraditional way of including glass block design for your bathroom.
