if the trap is fitted correctly then there should be any smells at all. The trap maybe losing it's seal due to certain aspects. try and fill your shower tray and then release. The seal mayb either 25 mm or 75 mm, if its connected to the soil pipe which u say it isnt, then it wont need to be 75. However, if there is other waste pipes joined to this waste (from sink, bath etc) and it's only 25 mm then it might pull out the seal, a deeper trap would do it..
