Wire size is based on the amperage the device draws. The wattage of the unit has to be included in the equation. Amps = Watts/Volts. Most homes in North America today are roughed in with a two conductor #10 cable. This size wire will allow a 30 amps. The electrical code allows this conductor to be only loaded up to 80% capacity so useful amperage is 30 x 80% = 24 amps. Watts = Amps x volts = 24 x 240 = 5760 watts. If your dryer's wattage is no larger that this a #10 conductor will be fine. If it is higher go to the next size wire which is a #8 rated at 40 amps. Same de rate has to be applied.

How far from a laundry tub faucet should you install an electric dryer outlet?

There is no requirement on the distance the dryer must be from a sink. Any 120 volt outlet must be GFCI protected if it is within 6 feet of a sink. There is no requirement for a 240 volt dryer outlet. I would not want the dryer right next to the sink and I would want the dryer to be on a 4 wire circuit and not a 3 wire circuit. Use common sense here.

Can you install a dryer outlet using the bare copper as a neutral wire in an older house?

Technically, yes you can. However, this is one of the most dangerous things you can do in electrical wiring. It's not only against the code, it's a fire waiting to happen. Don't do it! Understand, the neutral wire is a conductor. It carries current. It needs to be an insulated wire. Also, if you use the bare copper (ground) wire for a neutral, you have taken away the earth ground from the circuit, eliminating short circuit protection. If the dryer motor shorts out it will burn up. (fire again) A residential dryer requires a 30 amp 220 volt circuit breaker in your panel and a # 10 gauge wire with three conductors (insulated) and a bare ground. Have a qualified electrician install it.
