Thanks cfl.

Here's what I added to product.tpl directly underneath the product weight box.

<tr>
              <td class="property-name">Dimensions</td>
              <td class="property-value">
              <span id="product_dimensions">Length: {$product.length}, Height: {$product.height}, Width: {$product.width}</span>
              </td>
            </tr>

Works a charm . Hope someone else benefits from this!
