I recently installed the Aston Coraline 44 - 48 in. x 76 in. Completely Frameless Sliding Shower Door in Polished Chrome, with my brothers help and his wife. It took about 2 weeks to complete my main bathroom because it was a complete renovation.  The Aston Coraline 44 - 48 in. x 76 in. Completely Frameless Sliding Shower Door in Polished Chrome,  was a little tricky for a newly DIY person, thankfully my brother installed his and  we had mine up in no time.  Just 1 problem,  I have to purchase another one for my back bathroom.  I would recommend this item to family and friends.  
The door slides easily,  doesn't jump. No leaks, no more wet floor from a shower curtain.  I'm in love with this shower door.
