The postage... 

Bring your rusted one to local shops selling mixers. Some may carry spares and might be willing to sell you.

Will plumbing tape be enough or need to silicone or something heavier?

Plumbing tape not suitable. All mixer/tap usually come with a rubber or silicone washer for this purpose. Check your fitting between the basin hole and this rubber washer. Sometimes the hole is too big or mixer base & rubber washer too small. If the gap is very small silicone glue may do the trick.

Problem now I have a 3 yr old toddler, keep playing with the tap. I'm afraid he might burn his hands, so I had to resort to locking the toilet door for now.

water heater max temp is 60 degrees. should be not easy to get burns. Though i can understand.

Used to have a mixer for the sink. But no one ever uses the hot water and the mixer is forever on the cold side.
I guess the main issue is the length of pipes to the water heater. By the time you wash your hands, the hot water still has not yet reached the faucet. Unless you let it run out like the shower which really waste a lot of water just to wash hands or brush teeth. 
I have insulated my pipes with Aircon insulation foam when I renovated. I guess the insulation only helps minimize heat loss during use. When the hot water sits in the pipes for sometime then the heat will be loss anyway.  

So now I only buy cold only taps. 

I don't use it to wash my hands. I use it to wash my glasses. So it's very helpful for me. I use everyday.
To reduce water waste, I use it after I've showered. And the pipes already have hot water inside. Then it just takes 1-2second for the hot water to reach the basin tap.

If at kitchen sink, its helpful in degreasing stuff. And u can always use the water to wash anyway. 

To me, it's a must have just to clean my glasses.

Heavy rain the whole night, ended up my door bell went ding dong none stop because  of water sippage, I have to resort to "crawling " up a ladder to unmount the batteries early in the morning.   Went to buy a new Legrand outdoor doorbell button casing.

 

 

The  two rubber seals of the existing one are badly damaged.

Put back the new one. Looks ok so far, the wire seems to be a littel damaged, hope no more short circuit when it rains.

Not really, the most 2 or 3 year. These rubber get deteriorated very fast under hot sun, I bought a similar casing before  just to use the 2 rubber seals but now I decided to replace the entire casing now. Maybe have to look for more lasting one. Yes applied silicone at the back around the edges.

 Thanks

Still prefer SS sinks

I had mine for 20years in the old place maybe used it 1-2 times. The rest of the time was to exercise the mixer so that it doesn’t jam on the hot water side. 
maybe some do use it. But I really cannot think of anytime I would use it again. 

anyway all these years I have been using only cold water to wash hands and face. Kinda feels weird to use warm water. I guess only in temperate countries where the cold water is really cold does the mixing of hot water comes in. 

For the hot/cold mixing, now I plan to put this kind of thermostatic mixer near the water heater output pipe and mix with cold water.

Then I'll cut/block the existing cold pipe and reroute the "mixed" output to it to my MBR toilet. So that cold pipe essentially bcums warm (due to the mixer. It'll go to wash basin, shower, etc. The existing hot pipe will be blocked. So no more cold water, just a single pipe with warm water. I'm expecting turning on the tap initially will get cold water, until the warm water comes in.

I'm just wondering why run 2 sets of pipes when a single "warm" pipe will do ? Is there anything I'll be missing ? I don't think I'll miss that "cold" pipe.

All premixed at source and same temperature - flushing system will waste hot water, maybe wash body temperature OK, wash behind too hot, wash hands too cold....

How long will be the pipe runs. 
IMHO like I mentioned before for sinks it’s a waste of time. Unless you really use a lot of water at the sink every time. Cause to wash hands, it is at most 1l and by the time the warm water is flushed thru you are more or less done. 
Also you need to have the storage heat always on. That can consume quite some power. The biggest energy consumption in the house will be heaters and coolers, like water heater, refrigerator, Aircon. 
heating water takes a lot of energy. 
is the local room temp water that cold for you to need to do so? 
my suggestion is to measure how much water you use in washing hands and typical use at the toilet sink. Can be easily done by placing a basin and then measure the amount.

About 4m run to the wash basin. Same pipe also tee off to the kitchen single valve tap, but that's not important. 

Bidet tee off, if too hot for washing backside, then I dial down the temp. 😂

Waste of hot water in one toilet small cistern, but probably not too much.

I'll try first. If too much electricity, then I revert back.

I kaypoh and did some calculation. https://rechneronline.de/chemie-rechner/mix-temperatures.php

so with the water heater set at 70c to get 38 you need approx 25% hot water. 
so what you can do is roughly calculate how much water you use. Then 25% of that is hot water.

Wow that’s long. I guess in the end, how much more electricity will you be willing to pay a month. I would think it will easily be an extra 2-3kwh of power a day since you  leave it on 24/7.

old pipe was dripping in 2 places

so I decided to cut that leaky section and replace with a full bore valve and a spin down filter
