I have a one piece fiberglass tub/shower. I just noticed when I took a bath the other day that it was flexing when I moved. I thought it was going to crack or something. I did a little investigating and noticed that the tub has a support that runs the length of the tub on both sides. However, I don't think there is any support in the center. I went to ********* and they suggested a spray some expanding foam underneath the base. Last night I opened up the access panel to the hot and cold valves and tried to see if I could see under the tub. There appears to be a reinforcing brace across the width, but does not make contact with the floor (about an inch clearance). I proceeded to spray the foam under the base using a 5 foot piece of plastic tubing. The problem is I can't see how much foam is being released. Therefore, I can't see how much the foam has expanded. Do I just keep sparaying foam underneath everyday until the flexing stops or do I just call a plumber. I'm a big guy about 240 so I'm very concerned. I a take a shower it flexes but it does not sound like its going to crack. Any suggestion would be very appreciated.
Thanks
