He noted that the valves and shower head should not face toward the shower -entry. I would like to note that I had installed the shower and its plumbing work in accordance with the shower suppliers' installation instructions- a copy of which is attached. However, since his concerns may be "code" related which I assume pertain to safety issues, I have looked into ways to remedy this situation and considered three options. I have attached a sketch showing a plan view of the present situation and of each option. One of the three options was chosen as the proposed remedy because of the following reasons; o Straight access to the valves would be made impossible and thus safer. o I believe the remedy would make access to our shower similar to "code approved" corner - showers which have their doors placed on the diagonal. o the other options have practical limitations, would be costly and not any safer. o the least costs would be expended with no delays. o all the new plumbing work has already been pressure tested and checked for leaks. Additional plumbing work invites opportunities for leaks. I would appreciate your reviewing this proposal. Your acceptance of this proposal (and if you wish, together with any comments that you may want to add) - would be very much appreciated. Once approved I will keep a copy of it together with the other permit documents on site. Your Faithfully. AW dif/Y Marius Smidt. r Ins CO e uL Showers S how Stalls IMPORTANT!
