SunTouch is not made in custom sizes, because our 67 different standard mats can fit ANY space. Start with the right sized mat (We will help if you want!) and then cut the orange weave to make right or left turns, 90 degree turns and U-turns. You can install around any obstacle in your room - a column, heat vent, kitchen island, etc. but, never cut the blue heating wire. By making these turns, and sometimes pulling out the blue heating wire from the orange mat to fill small, curved or angled areas, you can precisely heat any size or shape room. You can see hundreds of example room drawings in our Design Library. The Design library can help you choose a layout that closely matches your floor plan, and you can order right away!
