Most contractors/ids will recommend you to tile up full height kitchen because that's where they can earn a lot. Labor for just tiling our small toilet/bathroom $1k liao. Honestly, labor cost only about $100 to pay 1 worker for 1 day, but then it's 'the market rate' so LL.... There's a conflict of interest with ids and homeowners coz ids are out to maximize profit while homeowners are out to maximize quality. Tempered glass would be impossible to drill through coz you will cause the glass to lose integrity, then if it is near the cooker, slight expansion at the screw points, you will likely cause it to crack. We opted for stainless steel coz it can be drilled through(need the stainless steel people to do it coz normal drill cannot punch through it unless your sheet is very thin). Also it is easy to clean, no expansion problem, no rust, no stain... if scratched, since it is matt, it'll look like part of the design. ;P Yah, for counter height, there's a certain optimal height. Ours is 44 inches. Any higher and you might not be able to lean your weight on it even if you just standing. You can go ikea to check out their counter heights. They make it very comfy for most people. Yups it's a perfect place to have breakfast or if you have guests and they want to sit and talk to you while you prepare a meal. =) We have yet to find the bar stools we want yet.... the ikea ones have black legs and not hydraulic so we not keen on it. Probably get a splash of red chairs from vhive. Budget less than $100 if possible. haha
