My builder grade bathroom vanities have seen better days. When I looked into replacement options, I was shocked at the expense for anything quality/high end, to the tune of $1,000 and up. For next to nothing, I reused my bathroom cabinet (painted it ) and poured a concrete counter top. Add a glass bowl sink, a farmhouse industrial faucet and you have an updated look for around $150.  Another affordable option would be to build open wood shelving for under the countertop, a future project for the master bath. Note – we have poured countertops inside, installing directly on the cabinets and in place but we’ve also tried it outside…
