I am installing conduit for a hot tub. I have conduit coming up from underground at the edge of the slab and I wondering how to transition it to liquid tight flexible conduit on top of the slab. The poorly drawn image below illustrates what I was thinking of doing. Is this ok or would it be better to bend the conduit or use a 90 degree over the corner and use a straight connector to join the pvc to the liquid tight conduit? I am planning on using 2' x 2' deck tiles to cover up the slab and the conduit after everything is installed. Thanks.
Your plan will work but depending on the distances in each direction, pulling the large wires that a hot tub requires could be tough. Think about using a PVC LB similar to the one pictured below. It's neat and clean and you can pull wires much easier with the LB access. You would have to stub a small piece of PVC to the LB and use a female adapter to accept the liquid tight straight connector(Thanks to @ThreePhaseEel).
